How to set different cut value for different physical(or logical) volume?

  I want to improve the efficiency of the program, so I want to set different cut value for different physical(or logical) volume.

eg. for e+ of 1.0Mev, if it is in absorber, because the absorber is thick enough and it can't transport through,I can terminate the track.Howerver, if it is in sensitive detector, because I am concerned about it,I cann't terminate the track.

Now I have a method. It is that I can terminate an unuseful track by judging the energy and the volume in every step. Apparently, the method is not good, because the judging time maybe more or the improvement efficiency is not good.

  I wonder whether I can set different cut value for different physical(or logical) volume and how to achieve.

  Thanks!
