I don't think you can actually check the poges you swap for. The only information you get is from the moves it used against you and possibly the item if its an activated one.
Normally I just pick up good looking ones along the way, if I was cursed with bad luck at the start and got some crappy poges. I find Heracross is a nice poke to work with in the BT because it has nice coverage with the decent moveset (most of the Factory movesets suck balls), so I usually pick it up if I don't get one at the beginning and if I encounter it along the way.
