So, I've got the build plan, which follows the `master` branch. I've configured the plan to create a new plan branch When new branch in repository is created and matches expression: (rc-).*
This corresponds to a release candidate branch, eg. rc-1.2.3
Now, the problem is that when I want to create a Deploy plan, I cannot set it to trigger upon a branch that matches a certain expression:

So, if I want to deploy a release candidate version to an isolated testing environment... I can't! At least not automatically...
Soo... what are my options here?!
