Can we use more than 2 runways @ Simflyers' KORD w/ AFCAD2?

I am using Simflyers' KORD AFCAD2 with the airline parking assignments, but since by default only 9L/27R and 9R/27L are activated, after a few minutes, there is a big traffic jam both in the skies and on the active taxiways going to the active takeoff runways. Apparently, since the flight schedules are true to life (using Ultimate Traffic), so are the aircraft movements and two runways active for takeoff and two active for landing are inadequate for O'Hare. In reality, 32L is used a lot as well as 4L and 4R.So in the end the other AI aircraft in line for takeoff and my aircraft are sitting there for a long time and after a while, they start disappearing one by one because there are 6 aircraft on approach and no one's being cleared to takeoff until there is a break in arrival traffic (which never happens - this is O'Hare after all!). Any way we can do this? Thanks Simflyers for a great scenery for my hometown airport!
