What is the best way to change an sprite's position inside a GO?

I was looking for a way to move a spinemodel inside a game object. Since sprite and spinemodel are both components I’ll just assume the same rules apply. Trying to rotate a spinemodel or a bone inside a spinemodel.
Rotating the spinemodel being rulled out, is there any way to spine.rotate_bone? Or maybe in future development? Besides the spine manual and api, where else (source?) should I be looking for ways to have bones rotate?
