Exterior wall boundaries with a boundary condition of Ground are not automatically assigned during the Intersect/Match, even if they are below z=0 I believe. Assigning these surfaces are done manually via the inspector. If you have a wall partially underground, you can bisect the wall surface by drawing the estimated ground profile on the surface. This will allow you to assign two separate boundary conditions to the wall, and two separate constructions if applicable.

I forgot about the measure that David mentions below.

An existing measure assigns boundary conditions per floor that could be a starting point for a measure that does the same with respect to z=0.
