Good Morning.  Im in the process of integrating the Foundations Library and just realized there are no Sink parts noted in the materials setup.  Sinks parts seem to be now part of the Base parts.  

How do i setup a project with sink parts specified with different materials then my base cabinets?  I want my sink parts to be produced with a plywood core, and my base cabinets with a melamine core.  The way the Foundations is setup i only get to specify the materials for Base Cabinets.  There are NO sink parts in the menu. 

Do i have to create a Sink Specific Construction Method?  This is not ideal by any means.
