[Inkscape-docs] Creating a separate GitLab merge request

I recently made a merge request for changes to the Beginners' Guide intro chapter. I'm making changes to the next chapter and committing them, but I want them to go to a separate merge, because Maren wants a separate MR per chapter. I don't see how that's possible. Can I have multiple MRs or do I have to wait for you to approve the existing one?
