Excluding tickets from search based on updated fields?

We have the following canned search, which will find tickets not updated by
the Current User in the last two days. This search is used in a dashbord
that sends a daily email to our support staff, showing tickets that need

Owner = ‘CurrentUser’ AND LastUpdatedBy != ‘CurrentUser’ AND
LastUpdated > ‘2 day ago’ AND Status != ‘resolved’ AND Status != 'answered’
AND ( Queue != ‘Development’ AND Queue != ‘Bugs’ )

The problem that we’ve run in to is that there are certain things that get
updated that don’t merit follow up – changes in ticket priority, or
setting Custom Flags.

Is it possible to exclude updates of certain fields?
