Rebase with auto squash

[apartridge]

We currently use Mergify with queue action, with

update_method: rebase
method: merge

to merge PRs into our master branch.

This gives us a linear history with merge commits. We also during the code review process push fixup commits (git commit -a --fixup HEAD) with fixes to comments, to facilitate easier review. When review is done and the author is ready to merge, the author squashes the fixups with git rebase -i --autosquash and force-pushes. It would be very valuable if it was possible to invoke auto-squash via Mergify. As of now, the user needs to checkout the branch locally and do this, which is a bit tedious.

It would be great with a queue action option that makes Mergify rebase with --autosquash. Another solution might be an option to the rebase action to enable autosquash?

That's on our roadmap, we already track your interest in this feature.

This is officially supported and enabled by default.
