Great idea! I've heard several similar requests as well. In the meantime, instead of waiting for the IAP to create the group in AirWave, you can create the group prior to the IAP coming online -> that way it will have the desired reg domain, overrides, etc. Another feature to make use of is the 'duplicate' feature on the Group -> List (far right column). There are limitations to the duplicate group feature, but it will at least copy the main group basic settings.
