It has often been asked that we can use Graphic Overrides to modify just one skin in a wall rather than the entire composite.
It seems that is not possible for the moment at least.
However I think it would be a good alternative to have a GO for the skin type - core, other, finish.
We can already control these by Partial Structure Display - turning the entire skin on or off as needed.
So what about having an option in the GO to override the view of these skins?
