[REQ]Ability to reset current threat

[Ambrusius]

We have found that in fights where threat is an issue (onyxia) we cannot trust the threat meter at all after a while, is it possible to get a macro to run to wipe all threat? then we can use that while the boss is on the tank as a sort of baseline for dmg from that point. thank you

This would be really excellent. Fireballs make threat un reliable. being able to manually reset it as P3 started would make this an invaluable tool. Similar with Wrath of Ragnaros
