@marcan it can, but it’s a MR strategy. I forget some people want their MRs to be squashed separately from the merge process.

The config I prefer as a GitLab repo owner is to do squash merges with semi linear history, and then the merge button does that for you (and you can rebase in the UI without the command). This is so easy to work with and is the best of both worlds because you can always look at the pre-squashed history in the MR.
