Feature request: Git Co-author

For companies that do a fair amount of paired programming, it's valuable to be able to represent multiple authors for commits. So we use Git's co-author feature:
https://help.github.com/en/articles/creating-a-commit-with-multiple-authors#creating-co-authored-commits-on-the-command-line

It would be great if this was a feature with these capabilities:

- Have a step in the CLI that asks for a co-author (after everything else?)
- Automatically add the bash profile in context as one of the authors (if additional co-authors are selected)
- Automatically add co-authors via global config (workstation) and/or project config
- Provide list of easy to add co-authors via global config (workstation) and/or project config
- Co-author tag for custom commit message template
