<!-- This issue template can be used as a great starting point for feature requests. Learn more about the process: https://handbook.gitlab.com/handbook/product/product-management/#customer-feature-requests. The first section "Release notes" is required if you want to have your release post blog MR auto generated. Currently in BETA, details on the **release post item generator** can be found in the handbook: https://about.gitlab.com/handbook/marketing/blog/release-posts/#release-post-item-generator and this video: https://www.youtube.com/watch?v=rfn9ebgTwKg. The next four sections: "Problem to solve", "Intended users", "User experience goal", and "Proposal", are strongly recommended in your first draft, while the rest of the sections can be filled out during the problem validation or breakdown phase. However, keep in mind that providing complete and relevant information early helps our product team validate the problem and start working on a solution. -->
### Release notes
<!-- What is the problem and solution you're proposing? This content sets the overall vision for the feature and serves as the release notes that will populate in various places, including the [release post blog](https://about.gitlab.com/releases/categories/releases/) and [Gitlab project releases](https://gitlab.com/gitlab-org/gitlab/-/releases).

Group level branch name template.
### Problem to solve
<!-- What problem do we solve? Try to define the who/what/why of the opportunity as a user story. For example, "As a (who), I want (what), so I can (why/value)." -->
As a group owner, I want to define a group level branch name template, so I don't have to do it for every project.
I'm hoping I'm filling this out right.

### User experience goal
<!-- What is the single user experience workflow this problem addresses?
For example, "The user should be able to use the UI/API/.gitlab-ci.yml with GitLab to <perform a specific task>"
https://handbook.gitlab.com/handbook/product/ux/ux-research/user-story-mapping/ -->
In a new project under a group, when creating the first issue, the users' flow shouldn't be interrupted by "can't create branch", due to the fact that the branch name template hasn't been created yet for that project.
### Proposal
<!-- How are we going to solve the problem? Try to include the user journey! https://handbook.gitlab.com/handbook/marketing/journeys/#user-journey -->
Correct below if I'm doing this wrong, I haven't mastered any of the journeys. :sweat_smile:
- Install
- UX
### Further details
<!-- Include use cases, benefits, goals, or any other details that will help us understand the problem better. -->
Currently, on a group level, you can only set the "Branch name" (found in a group, under Settings → Repository → Pre-defined push rules).
E.g. one could have this regular expression under "Branch name": `(feature\/.*|hotfix\/.*|bugfix\/.*|support\/.*|master|main|develop)`
By default, a new project doesn't have a branch name template, and an empty one wouldn't match above regex (unless it for some reason is called `master`, `main`, or `develop`).
This ruins the flow in the start of a project, when creating the first merge request from an issue, because it creates a branch in the format `%{id}-%{title}`, which doesn't match above regex.
Therefore, if a group level branch name template was available and set (not empty), projects in that group would inherit it, so that it could match the group level "Branch name" setting.
Project would then create branches with, e.g., this format: `feature/%{id}-%{title}`, and would not interrupt GitLab flow when creating the first issue and merge request in a project.
### Permissions and Security
<!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)?
Consider adding checkboxes and expectations of users with certain levels of membership https://docs.gitlab.com/user/permissions/
* [ ] Add expected impact to members with no access (0)
* [ ] Add expected impact to Guest (10) members
* [ ] Add expected impact to Reporter (20) members
* [ ] Add expected impact to Developer (30) members
* [ ] Add expected impact to Maintainer (40) members
* [ ] Add expected impact to Owner (50) members
Please consider performing a threat model for the code changes that are introduced as part of this feature. To get started, refer to our Threat Modeling handbook page https://about.gitlab.com/handbook/security/threat_modeling/#threat-modeling.
Don't hesitate to reach out to the Application Security Team (`@gitlab-com/gl-security/appsec`) to discuss any security concerns.

### Documentation
<!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/development/documentation/workflow/#for-a-product-change
* Add all known Documentation Requirements in this section. See https://docs.gitlab.com/development/documentation/workflow/
* If this feature requires changing permissions, update the permissions document. See https://docs.gitlab.com/user/permissions/ -->
I suppose a change must be made here: https://docs.gitlab.com/user/project/repository/branches/default/
Or perhaps a new section in the documentation about branch name defaults, if the same naming and location as projects is used (eg. in a group: Settings → Repository → Branch defaults, which would be the same from a project).
But I assume it can be put into the thing I linked to.
### Availability & Testing
<!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier.
What risks does this change pose to our availability? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing?
Please list the test areas (unit, integration and end-to-end) that needs to be added or updated to ensure that this feature will work as intended. Please use the list below as guidance.
* Unit test changes
* Integration test changes
* End-to-end test change
See the Quality Engineering quad planning and test planning processes and reach out to your counterpart Software Engineer in Test for assistance.

### Available Tier
<!-- This section should be used for setting the appropriate tier that this feature will belong to. Pricing can be found here: https://about.gitlab.com/pricing/
* Free
* Premium
* Ultimate
-->
I suppose the project aspect of this feature is already on the `Free` tier, so I will assume that. Otherwise, I, along with my team, would greatly appreciate it if it were on `Premium`.
### Feature Usage Metrics
<!-- How are you going to track usage of this feature? Think about user behavior and their interaction with the product. What indicates someone is getting value from it?
-->
I'm not sure how GitLab will track this, but here is my assumption:
- A group owner (or one with permissions) creates a group level branch name template
- Someone creates a project, an issue, and then attempts to directly create a merge request, without changing settings
- The new branch and merge request are created with the specified group level branch name template
The last two steps I assume can contain places that can track whether the first step is effective.
### What does success look like, and how can we measure that?
<!--
Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this.
For a guide, see https://docs.gitlab.com/development/internal_analytics/internal_event_instrumentation/quick_start/
-->
- [ ] A group owner can create a group level branch name template
- [ ] Someone with permission can create a new project without changing any settings
- [ ] Someone with permission can create an issue in the newly created project
- [ ] Someone with permission can create a merge request from the issue
- [ ] When the merge request is about to be made, it displays the branch name in the group level branch name template format
- [ ] When the merge request is made, the branch is named according to the group level branch name template format
### What is the type of buyer?
<!-- What is the buyer persona for this feature? See https://handbook.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/roles-personas/buyer-persona/
In which enterprise tier should this feature go? See https://handbook.gitlab.com/handbook/company/pricing/#three-tiers -->
- [App Dev Avery](https://handbook.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/roles-personas/buyer-persona/#app-dev-avery)
- [Platform Perry](https://handbook.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/roles-personas/buyer-persona/#platform-perry)
- Maybe [Program Management Payton](https://handbook.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/roles-personas/buyer-persona/#program-management-payton)
Free tier would be :star_struck:, otherwise Premium tier would be :partying_face:.
### Is this a cross-stage feature?
<!-- Communicate if this change will affect multiple Stage Groups or product areas. We recommend always start with the assumption that a feature request will have an impact into another Group. Loop in the most relevant PM and Product Designer from that Group to provide strategic support to help align the Group's broader plan and vision, as well as to avoid UX and technical debt. https://about.gitlab.com/handbook/product/#cross-stage-features -->
### What is the competitive advantage or differentiation for this feature?
### Links / references
<!-- Label reminders
Make sure to add the appropriate labels for the product stage and/or group (e.g ~"devops::plan") if known and add a comment tagging the appropriate Product Manager.
