How to record the energy deposition of each voxel micro-element in the DICOM example

I intend to define each voxel in the model created by the Dicom example as an SD, and thus to obtain information about the particle re-voxel microelements in one experiment.

I would like to follow the process of constructing the HadCalorimeterSD in the B5 example by calculating the hitID to access a specific Hit.

However, this process requires the GetCopyNumber method, but I understand that Dicom uses G4PVParameterised to build the model, can the model built by this method use the GetCopyNumber method?

If I can use the GetCopyNumber method, which direction copy number of the physical volume does 1, 2 and 3 correspond to?
