This was requested in a thread a few weeks ago and we got a very vague "Wait and see." response from a developer. I imagine that translates to it is in the works, or at least on The List.
Would only work if it auto-announces any no drop items to the group instead of even trying to loot them, with what corpse it's on. IMO.
I would much rather they add a loot filter so that we can add the option to never see certain items again unless we wanted to.
