That's exactly what pre-outs are for. Check the manual to verify the specific intended function, but pre-out should work fine for what you want to do.
My receiver has pre-outs for all seven surround channels and also pre-outs for two additional zones so you just need to know if there are any settings that you need to make to get it working the way you want.
