Is there a way to change a physic constraint that is inside a physics asset with blueprints?

I created a skeletal mesh with an physics asset. Inside the physics asset I created a constrain. I try to set the “Target Orientation” for this constrains with a blueprint. But the only node I can find is “Set Angular Orientation Target”. This only works for physics constraint components.Is there a way to do the same thing on a constrain that is inside a physics asset?

Did you ever figure this out?
