email notifications on Updates made 'on behalf of' don't say that they were made by someone else

We routinely run reports logged in as a person in that Team, when sharing a screen in a meeting, and make Updates that accurately say "Jeff Rowe on behalf of Abigail Geisinger" which is great.  The email that alerts the user (in this case a colleague who is being asked for something) does not include the now-important part, that a PM made the remark and not the user who was lending us their persona.
