That sounds like that would effectively do the same idea =)

Only reason I thought of it was because I had turned on "Accept ANY quest" thinking it would make things easier while questing, but then when I stepped in WG raid someone shared the collection quest that I didn't want to do, so I ended up finding it in my log later on and abandoning it and turning off the "Accept ANY quest" after realizing that it did, indeed, accept ANY quest. LoL. Sounds like you've got a good alternative solution in mind =D
