Commit preserving auto-merge

[Rosuavio]

The auto merge tool in github relies on the github merge methods, I don't like them because they dont use the same head commit from the branch.

I need some other method to automerge that does use put the same HEAD commit from the PR to main (probably something that uses git commands under the hood).

I need this for when I want to auto-merge my hand written changes and auto generates ones from github actions.
