Character Animator Null Object to AE

Hey everyone.
Here is my Problem, maybe you have a better solution.

I rig and record my character in Character Animator and then to finish the scene I want to work on in After Effects. Here it would be nice to have the position of the hands (which are moving).
Is there a good way to do so? I guess there is no way to get the motion data or like a Null Object from Character Animator to After Effects. Or is there?

My work around at the moment would be:
Give my character a symbol of a "Tracker Point" in the Hand and then Track it in AE, but this is a lot of work and not always satisfying and precise enough...

Is there a way to get "raw data" out of Character Animator to AE?

Cheers Julian
