One thing Unity has for 2D animation is an area of effect tool for bones, so we don't have to create so many separate elements, but can more easily edit a 2D sprite's hair without affecting other areas of the sprite.

Does CTA4 have this feature and I'm just not aware of it? If not, something to for sure make for future updates:
