May have to revert #25 , there are problems if your enterprise org uses teams and within these teams have access to different repos. I no longer have access to github enterprise through work can't debug.

I think it's better to revert features if core maintainer cannot support them to completion.

If anyone is able to solve this I would be more than willing to accept PRs.
