Add possibility to select the specific repositories you want to execute the command in.

Lets say we have the following:
source folder:
Repo 1:
Repo 2:
Repo 3:

And I would like to be able to only execute the command in "repo 1" and "repo 2"

Yeah, it is one of the most prioritized feature for the next release
