XDJ-RX2

Ok, so i already have a Rane SL4 and usually play timecode vinyl through my Numark m6 usb mixer and of course laptop. Looking at getting the XDJ-RX2 mainly for the fact that i won't need a laptop and it has loads of functions and i won't always need turntables. But as an odd on feature, what I'd like to know is can i connect my decks into the phono line and still hook up my sl4 via laptop and play timecode vinyl, just like i do with my prehistoric numark mixer. Im not interested in all the bells and whistles when mixing vinyl, just hoping to also use rx2 as standalone mixer simply for beatmixing when i want to spin vinyl.
