We currently use the 'run' command the most (e.g. "/gitlab a_project run a_ci_job" Now, in most of our project repos the CI pipeline has several stages and several jobs per stage It would be great to be able to 'run' a specific stage or even 'run' the entire pipeline https://gitlab.com/groups/gitlab-org/-/epics/7536
