Specify build-only branches from web UI


I’m working on transitioning a large and active application to circleci from travis, and want to prevent builds (and broken builds) from appearing outside of a feature branch until the the transition is complete (the application required some changes that are not compatible with travis without a lot of work, so it’s currently one or the other).

I can commit a simple circle.yml file to master and all open branches, but I’d prefer not to, especially if the transition doesn’t work out.

Is there currently a way to set the equivalent of

      - feature/my-branch

from the web ui, instead of requiring the build config file?
