Placeholder for the name of the gitlab repo

I'm using gitlab with JIRA and making use of the placeholders. My project URL looks like this:

project_url: "http://jira/issues/?jql=project=:issues_tracker_id AND labels=puppet"

What I'd like to have is a placeholder for the local repo name (in this case "puppet") so that I can do something like this:

project_url: "http://jira.apptio.lan/issues/?jql=project=:issues_tracker_id AND labels=:gitlab_repo_id"

That way I can link each new gitlab repo to a label with the name of the repo.
