How to put a graphic EQ and the dual combinator on mic groups?

Hey folks! I've been working a lot of soul-sucking corporate gigs lately with groups of different mics ( 2 pod, 3 lave, 4 HH kinda thing). I've been having great success with putting all the same kind of mics in groups and then running those through graphic EQs. I'd also love to throw the dual combinator on each mic group to even things out a bit. Any tips?
