Label sources

Hello,

I would like to ask if there could be a possibility to add a "Label sources" functionality.
Our current project requires some files to be modified during the build process, then commit back these files, and then place a label on this commit.
For the commit during build feature we use your extension. It would be nice if your extension could add a label after the commit completed.
Can it be done?

Thank you in advance!

That wouldn't be too hard I suppose. I'd accept a pull request in this direction.

Not sure when I'll have time to do it myself.
