Routing question with Presonus 1818VSL

So here's my question:

I've set my DAW PC up so that my output (instead of the sound card) is going to my ASIO Presonus (Output 1/2 - aka DAW 1/2) and it appears in the AudioBox Control panel and I can play it through my FOH and stage monitors with no issues.  Considering that DAW 1/2 are returns, how do I get this back into SONAR so I can record it on a track.  The reason I ask this question is that I queue up the backing tracks in either iTunes or VirtualDJ (it's quick) for live gig situations, but wan't to be able to record the track as well.  

Any ideas / workarounds?
