Thanks for the reply, I knew about that setting which really isn't a problem. It's more of a re-structuring my key maps problem if added to my team.

Another problem would then be the setting on the character set - "Mute background game window audio and un-mute foreground window audio". I currently run with that checked as listening to sound from all 5 accounts is horrid. So I don't think I would be able to hear my AH account, as he would now be part of the same character set.
