Mix of all inputs to 1 audio track in X2 SOLVED

I'm trying to get a mix of several inputs of my 828 into one audio track in X2. I used to have an input device called "Mix Return" in an older Ultralite, but the option is no longer in devices available. I'm wanting to mixdown several external midi instruments at one time without having to use 3 separate audio tracks and then bouncing those 3 to 1. Any suggestions or is this a MOTU Cuemix software issue? Thanks. This was a MOTU Cuemix software set up issue, it's just called something else now, all is well.
