How to Serialize an AnimationState

Hello,

The main question: Is there any way to Serialize an AnimationState?

Simple code being:

 [SerializeField] private AnimationState animationstuff;

That doesn't show up in the inspector; Animation and AnimationClip do, however. The only reason I can think of is probably the different fields that go along with it.

Secondary Question:

If you CAN'T serialize an AnimationState, how would modifying the AnimationState's "AddMixingTransform" value carry over into the AnimationClip referenced? Would you be able to do that, or is serialization out of the question when it comes to animations?
