We recently switched to the Foundation Library from the Component Library.  Or standard drawer construction is dowel with captured bottom.  The sides had stop dados and the front and back had dados that ran past the ends.  The bottoms would be cut with square corners.

In the Foundation Library we were able to set up the dowel construction to match our current layout. The drawer bottom is in a dado- on four sides, but the front and back are set for stop dados that forces the bottom to have a notch cut out.  

I compared settings from the old to the new but am unable to find the setting to allow the dados to run through on the front and back parts.
