Grouping of repositories to work with aggregated log graph (checkout same branches, cherry pick to same branches in different repos)

I am working with a few repositories and usually have same branches and track same versions on them. It would be easier for me when I am able to select the repos into some kind of group and was able to checkout same branch for the group. Also the group provides view of a cumulative log graph of the branch, a cherry pick action for different repos' commits which end up each in own branch without switching repositories and cherry picking in each repository.
