I have a concourse pipeline which takes multiple branches as input.
Say branch1, branch2, branch3 etc.
When branch1 is pinned from ui and built it generated branch1-snapshot. On pinning branch2 it generates branch2-snapshot and so on.
It works fine.
Now I would like to save all the snapshot names in a repo or a in a file in a repo, so that whenever there is a need to deploy a particular snapshot version generated by my multibranch job, all i have to do is list out the versions available in this file/repo and give user the option to pin one version and hit the deploy button.
Is there a concourse resource which fulfills this.
Note: semver wont satisfy my requirement as the version will not be in a semantic versioning format.
