Turning Numark M6 usb"s audio interface into 8 output

Hi, I want to ditch the 8 output multiple cord mess, going from my Gigaport AG, into my Numark M6 USB, and use one cable via the mixers audio interface, to clean things up.
I know have no hardware options to do this, however are there software workarounds that would fool the 2in2out usb interface into thinking it has multiple outs?

Setup: One Numark M6 usb, Korg Nano Kontrol2, Gigaport AG, Macbook2009 with OSX 10.9, 2.0ghz processor, 3gig ram.
Thanks.
