Reply to Traktor S4/Vinyl Set up

Alright guys so I bought the Traktor S4 and I have been having a good time with it but I want to add to the beast.

I have recently acquired two vinyl turntables and I am wondering if it is possible to some how hook them up to my S4 using them as a vinyl emulation input, using the jog wheels for decks 3 & 4 and have the rest of the S4 running as normal. Is this possible? What extra hardware would I need and how would it be pieced together thanks!
