Histograms or Tupes for assembly volumes

Hello all,

I have a quick question with regards to geometry assemblies and analysis managers.

Having placed a series of repeated assemblies, I am hoping to extract energy deposited in a particular logical volume within each assembly and compare them. For example if my series of physical volumes include 2 placements of 2 assemblies with 2 logical volumes in each:

av_wwww_xxxx_yyyy_zzzz =

I wish to compare energy deposited in volume
av_1_impr_1_bLV_pv_1 vs. av_1_impr_2_bLV_pv_1

Since the ConstructSDandField method only takes logical volumes, would there be a recommended histogram method to create sensitive detectors based on placement volumes?

Thank you all for your time
