How to access to parallel world volume

I am trying to perform some action inside a volume defined in parallel world, but having some trouble.
A parameterised volume is defined in a parallel world. And in StackingAction, I tried to turn off every secondary electrons inside the parameterised volume.

So I added StackingAction in my code. And then by using G4track, if the particle is in the volume, the secondary electrons are turned off.
But It seems StackingAction class cannot return the parallel world volume, it always returns mass world volume.
(track->GetVolume()->GetName(); returns mass world geometry, not parallel world which I want.)
Is there any way I can perform this action?
