Reply to My new controller, need a little help! :)

As I posted, I was believeing to get a Mixtrack Pro as a controller, but, I just changed my mind, and I bought a Xone4D, it'll be here in about 2 weeks!
I just ahve 1 question, I'll use it with Traktor Pro 2, and I want to use it with 2 decks, each "Xone1D" for each deck, so I want the first deck on channel 1 of the mixer, second deck on channel 2 on the mixer, and channel 3-4 for my physic decks.
How can I do it?
I dunno what may I do, thank you very much
