Reply to Pioneer DDJ SX mapping help

I've been using the Traktor s4 for a bit now. I just recently acquired the ddj-sx and im using the traktor mapping for it. I'm missing the Loop section on the s4 a bit now. Like how you can select your loop size and browse through the track according to the size you have selected. I've been trying to map this function to the ddj-sx. Any help would be deeply appreciated.
