How do I cherry-pick multiple commits into MR?

I want to cherry-pick multiple commits from branch A to branch B in GitLab.

I know that I can create an MR for merging A to B, and I know that I can create an MR for cherry-picking a single commit from A to B.

Is there a way to do this in GitLab UI, or am I going to have to cherry-pick locally from A to C, push C to GitLab, then make an MR for merging C to B?

Thanks!
