Perma pets for certain tasks.

I was wondering if nexon, for the benefit of those that do not use the cash shop, could add a special pet (like a snail or something) that only picks up certain tab items, like equip tab, use tab, or etc tab items, you do a very long and tiresome quest, and can pick one of three pets for one account only (not one for each character though) one of a kind no trade to avoid abuse.

It would certainly be helpful for me since i already pick up scrolls and items i want manually already, and i would be making a bit of extra money without having to scoop all of it up myself.
