I don't think there is any way for it to check if your class can use it or not or if you already have a T2 BP that you clicked to transform to your class BP. I use Plure's Autoloot plugin and when I move to a camp, I see what drops there and go through the ini to add it in and state how I want it distributed.
Loot=Gear|Classes|WAR|PAL|SHD|BRD|RNG|NumberToLoot|1|
The plugin can't check stuff, but you can state it in the ini ahead of time what class gets what and how much. Like if the loot is casters only, you do
Loot=Gear|Classes|MAG|NEC|WIZ|ENC|NumberToLoot|1|
Or if it's prestige, you'd only put classes in there that you have that are gold. First to loot is the Masterlooter. Next to loot is who started the group and then the order in which next group invites.
I think it was stated in the plugin thread that next to loot is the Groupleader, but I changed group leader around before so that'd that toon would be second to loot and instead the toon I started the group with that initially did all the invites was still second to loot.
