Reply to Numark 4Trak & APC40 Mapping?

Hello!
I am new to the DJ TechTools Forum but have been reading the BLOG and using the resources for a while. I recently started DJ'ing, and I have a few questions about my controllers and mapping them. I started off with a Numark MixTrack Pro back in October. I figured that I needed a more powerful controller for Traktor, so I bought the Numark 4Trak last week. I also have the Akai APC40. I am wondering if you can use the 4Trak as the main Deck controller and use the APC40 as a remix deck or some sort of clip launcher? (Don't know the exact terms, sorry )
Any Information would be great! Thanks
