Is it possible to do Parallel Compression on Series 3 Mixer for LIVE mixing?

I have a gig coming up but won't get my 32r till prob day or two before the event... Leaving me little time to get my "feet wet" with it. I had the RM16ai prior. Can someone give me an idea of (if possible) how to set up parallel compression for (1) lead vocals, and (2) the overall drum sound (group)... I'd just like to blend the parallel compressed sound back into the lead vocal and the overall drum sound to "thicken it up" like I do when I am mixing a song in Studio One. Can I do that in a live situation on the Series 3 32r? Thanks :-)
