Assembly Drawing Table with Part-Level Family Table Parameters

I would like to create a table in a drawing of an assembly that includes family table parameters for each of the parts.  

I've created an assembly of a cabinet with multiple parts that include family tables.  These family tables all include the length and width of the parts.  I'd like to create a table in a drawing of the top-level assembly that pulls in the length and width of each part from their respective family tables.

I've included a simple graphic to help explain what I'm talking about.  Any help will be greatly appreciated.
