Deploy current local branch without manually specifying?

So basically right now if my local repository is on branch release/213 and I want to deploy I must use

dep deploy staging --branch=release/213

I know you can get deployer to deploy based off the HEAD on the host, but in this case with our releases this changes often so we'd like a config option to say "when deploying to host X deploy whatever branch we're using locally".
