SoundCue will let you do that simply.
"Adjusting cue volumes:
Press “Tools” and choose to unlock individual cue volume controls. You can use a slider on each cue button to set it’s volume. When you’re done making changes,
you can lock these sliders back using the tool menu to prevent accidentally adjusting them during a show."
http://www.soundcueapp.com/quick-start-1 Run through your sets, adjust as necessary(using your ears); freeze settings. The ones that are way too low you can adjust in a DAW and reload in SoundCue. That would be quicker.
What kind of places do you play? What are you using as a PA? Are you having a good crab season this year?
