Trim boundries/Check Data...

For NX7.5 is there a way to define trim and or check data for the path to avoid in a single operation? I can define Check Geometry at the Geometry View and Volumill will avoid the Check, but this does not help in the case of multiple set-ups while tracking the IPW.
Simplified, I want to control Check/Trim areas per operation. Is this possible using Volumill and NX7.5?
