In CAS, when editing the facial features, go ahead and mess around with the sliders in a category or two. Then, go to category you haven't been messing around with and pick one of the default selections at the top. Obviously, don't do this in the full face category, because then you'd be undoing all the changes you've made! For example, if you've messed around with the nose and the lips, pick something like, say, the eyes, and pick one of the default eye selections. Now go back to the categories you were messing with. You'll find that the sliders have reset, but the changes you've made remain. The result? The ability to mess with facial features to infinity.
