Feedback Access to Current SpriteState

My request is very simple, so much so that I cannot figure out why it doesn't exist and there are no workarounds to be found.

I want to be able to read what spriteState is presently in use so that I can make decisions accordingly.

I ran into this because, due to single graphic limitations on buttons, I had to separate my button's frame into a separate object. I want to edit this frame to match with the current states of the button, which requires me to be able to determine the presently active state.

I attempted to add this functionality myself, but with how tightly the related code is protected, I cannot. All it needs to do is update a string property that can be access with a ToString or similar call so we can have access to the present state...
