Wall types have a property to wrap layers at ends, and at the insertion of windows and walls. But that does not apply for what you need to do for this wrap of the finish at the joint between a wall and a curtain wall.
It is good practice for Revit walls to separate the structural part from the finish part. That means, creating the finishes with a thin wall type, independent from the core. This practice has two advantages:
1) All these issues about wrapping, joining, extending layers, in plan and elevation, are easy to fix.
2) For structural walls with finish, the engineer receives the structural elements, only, while the finish elements remain in the architect's model.
