title: Revert to older patch set version via the Gerrit UI?
body: <p>If I have multiple patch set versions for one change in Gerrit, it seems like I can only submit the latest patch set version (because only that one has the necessary button). Is there an easy way to instead <strong>submit one of the old patch set versions</strong> of the same change, using only my web browser on that Gerrit instance?</p>
  
  <p>I know that I can fetch the wanted version of the patch set from my git client and push it as yet another new patch set version on top, but I would like to avoid having identical patch set versions multiple times in the review and discussion around it.</p>
