Reply to Im so close!! (VCI-300 & Traktor Scratch Pro)

So i downloaded LiveFastStephen .tsi (http://www.djranking s.com/community /showthread.php?t=11030 btw thnx!) and mapped almost everything i needed to my VCI-300 (with a few edits of my own). Thing is a still have some unused buttons and i want a way to switch between the A and B decks. Does someone know what control name this has in the Assignment Table?! Any help and/or suggestion would be great. Thnx in advance!
