Cabinet Mass/Weight and how it currently works

The last discussion about cabinet weight I found was from 3 years ago. While I can get information about the cabinets from MV and put it in a spreadsheet formula and get the material weight of a project, but that is tedious. 
Does anyone know what the best way to get a weight estimate with the Foundation Library is? I saw a couple material weights in the global but don't know the right way to use or add more material properties.  Any thoughts, advice or links to relevant information appreciated.
