When trying to run a plan manually, it asks for revision or commit number/name. Often times, when running something manually, I simply need to run on a specific repository on branch master, HEAD.

This is why I think it would be useful to be able to simply add the repository name in the field, which automatically finds the head commit on the master branch, or simply specify the branch/tag via hashtag, like so:

rCDD

Or

rCCD#some-branch

Or

rCCD#someTag

Etc..

In my opinion, this would definitely save a lot of time looking through diffusion for the latest commit.
