Zone boundary excludes curtainwall footprint area.

Normally not an issue when curtainwall is used at exterior walls but it is when used at interior room boundary walls. The curtainwall footprint areas get excluded from the zone boundary/area. The excluded footprint seems to be fixed to the curtainwall's default size and offset location; it won't update when you change the offset distance or the frame sizes. Is there a way to include this ignored footprint area?

Curtainwall could be used for many things, like custom design screen walls, etc. but it's a big problem if the floor area calc will have to end up being wrong.
