How do you do a Smart Pet Search where you list all pets that are only available from the Trading Post, Promotions, or other source outside of the game world? The only smart search filter that seems relevant is "Found In Zone", but it only includes in-game map zones. And if there is currently no way...

Thank you!

Warcraftpets has ratings for individual battle pets' battling ability, but is there anywhere (here or elsewhere) where comps are rated? I'm noob battler, finally collected enough pets to start thinking about comps.
