How i can launch loops in Traktor?

Its anyway to launch loops (loops maked whit reason, ableton, etc…) in traktor 1.2? I have a maya44 usb soundcard, so i can only use 2 decks, so i cant use decks C or D to launch loops.

You can still use the 3rd and 4th deck you would just need to route it through the same channel as either a or b

I tryed it, but if i choose the same channel of a or b, in c, it unselect the route of the channel that is using that route.
Im explaining well?
