listen option function

So my plan is to make the system let u select where it needs to listen to for the trigger command
so if u run multiple wow accounts and someone whispers u with BNet it will give the replay more then 1 time

have had this my self already

so i want a multi-select dropbox where u can say where the addon needs to get its trigger from
disable BNet on alt for example so only 1 reply will be send
