Create an option to add a note onto a PUR in the editor when a change is pending for a higher level editor to approve the request.

There are several suggestions on being able to add reasons for why an update is rejected, but a method for the submitting editor to explain the reason for a change might be more effective in helping the senior editor make the decision to accept or reject.

This can currently be done with a map comment, but often those arent noticed when reviewing the PURs in busy areas or will remain on the map if not deleted after review.
