https://codereview.meta.stackexchange.com/questions/3772/vlq-review-queue-option-for-this-should-be-a-comment

I was reviewing an item in the Very Low Quality queue for Code Review (which I sadly cannot link to) that was most definitely not an answer and should have been a comment, because it was asking for clarification from the asker.

I understand that converting to a comment is a mod privilege, but there isn't even a way to get a moderator's attention from the review queue screen, something I believe would be an incredibly useful feature for those times when something needs to be handled by a mod.

I would propose that it act identically to the ordinary flag button.
