The GDL for wall ends (they are just objects) can only deal with composite walls (they may even be limited to only a few skins as well).
There is no way they can deal with complex profile walls that could have any configuration of fills an any number, shape or position.
Sometimes you can get them to work on a simple complex profile wall - but I wouldn't rely on them.
