This is not the first time I have run into this before, but it would be great to be able to move around the fill pattern used in families. We have a face based panel family that we use for all wall finishes we ever use. One of my coworkers was using it to represent a custom brick tiling in an auditorium. It made sense to do that instead of creating a new wall type just for this, but Revit wouldn't allow any sort of adjustment to the pattern alignment, even though the pattern was a model pattern. Revit should treat patterns everywhere the same so that we don't have to create multiple ways of achieving the same thing
