While in the SketchUp Plugin and switching to "Render by Boundary Condition" (to see changes) you can select individual surfaces and change the "Outside Boundary Condition" from "Outdoors" to "Ground", or any Ground+ processing option.
The surfaces reference a local coordinate system as far as I can tell while in a space block, so I would not know how tackle this from a measure perspective unless the surfaces also reference a global coordinate system somewhere. By this I mean some measure that would look for all surfaces with global Z-coordinates < 0 (below grade) and change the Outside Boundary Condition to Ground or whatever automatically. I believe this is the case in some programs where a space/ zone below grade automatically is converted to below grade constructions.
