Fader Start on DJM2000

I'm wondering if the Fadar start function is only for the crossfader. I would love to be able to just drop my cued up tracks on my players and when the time is right i can drop in the track solely by concentrating my focus ont eh mixer. 

In my opinion, it just seems like it should work with the Up Fadars as well, maybe not the back cue, but atleast fader start with the upfaders
