Is it possible to have different base extensions on either side of a wall?

[PDSF]

I have exterior walls sitting on low curbs with finish both sides. It would be great if I could set different base extensions for each side (one on the slab side, the other on landscape side). When I try to "unlock" the finish layers on the inside, Revit tells me that the layers must be adjacent. I assume this means that what I'm trying to do is not possible? Anybody have a workaround?

No.  But you can attach the wall to two different floors or roofs.  Or create parts and stretch parts differently.

The attach idea could work. Technically the finish doesn't want to extend all the way to the levels on either side, but it could be close enough to look okay. Thanks.
