Suggestion: Hide Rep from Rare/treasures after 1st time of war band looting it

[tfmonk]

it appears for some rares (possible treasures as well?) trigger a second quest on their first kill, i suspect this is for the rep for the war band tracking so you can only get it on the first kill.

Is it possible to track these additional quest ids and remove the rep gain from the tool tip to make it a bit more accurate after the initial kill so people know they wont get additional rep?
