First check the stepping action in the DMX underground physics experiment.
You can see there how the stepping action can be used for drawing the tracks.
You can add some extra checks before drawing like
if presteppoint volume is volume 1 and poststeppoint volume is volume 2 then draw
This would do it..
Also make sure that /vis/scene/add/trajectories is not issued. Otherwise Geant4's visulazation mechanis will also be drawing along your stepping action.
