title: Merge request with just one commit
body: <p><br/>
  I need to create a GitLab Merge Request to the master branch containing one commit which I have made on my fork.<br/>
  I have, however, already an open Merge Request to the master branch.
  When I try to create a new one, the pending commits from the (open) MR are also included.
  How can I specify in my MR to use only one specific commit? (and not the old ones) ?
  Will this work? <a href="https://docs.gitlab.com/ee/user/project/merge_requests/cherry_pick_changes.html#cherry-picking-a-merge-request" rel="nofollow noreferrer">https://docs.gitlab.com/ee/user/project/merge_requests/cherry_pick_changes.html#cherry-picking-a-merge-request</a>
  Thanks! </p>
