How to remove Last edit by for specific admin
 

Is it possible to prevent the "last edit by..." from appearing for a specific admin/user which makes them immune from the time limit set for a message to appear by the user who last edited a message?

As an admin, I would like to prevent my username from appearing as I do a lot of moderating of posts, but do not necessarily want the last edit to appear in the posts. Any help would be lovely. Thank you!
