Best practice for using @mention in a log rich text field.

Anybody have a best practice on using the 'Mention' feature in a log rich text field?

My use case is: A rich text field w/ log edits turned on is used as a collaboration tool for team members to provide updates and ask each other questions. They mention each other in the comments and receive an email when they have been mentioned, via the handy 'send to users @mentioned' feature in the new notifications (see image below).

However, when the 'Log edits' setting is turned on, Quickbase will email ALL the users who have ever been mentioned, when really we want just the person/people who were mentioned in the most recent comment. My workaround for this is to create a formula field to parse out the most recent comment and then a webhook or form rule to enter this value into another rich text field, with the @mention feature turned on. This last rich text field is used in the 'To' setting of the notification.

This is a lot of work to simply use the mention feature! Is there a better way to do it that I'm missing?
