Hey!

Is there a way to get a ref to work like an optional OR? For example:

// GITHUB_HEAD_REF being the name of the branch if my google-foo didn't fail me
ref: ${GITHUB_HEAD_REF} || master

My use-case: I have multiple repos that depend on each other sometimes. If they do, they all share the same branch name for a feature (e.g feature/add-tests). I want to pull the repos with those branches when they exist, but if they don't (as it's not always necessary to change code in all repos), it'll pull master.

Thanks!
