Reply to s4 hotcue 5-8

hey DJTT, i just purchased an s4 about a month ago and i have a couple questions regarding remapping.. is it possible to use the sample bank play buttons as hotcue buttons, re-assigning them to hotcue 5-8? if not, is there an easy way of getting my novation launchpad setup to control the 5-8 cue points in all 4 decks without disturbing the mapping of the s4? i've searched around the traktor bible and this site but can't find much information on using the two together besides having traktor and ableton in sync via midi.. i bought the launchpad for production but it would be very nice if i could use it instead of buying an x1 and pairing it up with my s4.

thanks in advance!
