Add a health modifier for headshots?

Hi people

I am not good with Dreams logic. I am trying to build a FPS game and I wonder if there´s an inbuilt feature to modify health damage depending on which puppet body part is affected. I particularly want to increase health damage when puppet head is hit.

My first idea was to attach an invisible sphere to puppet´s head and use it for that, but no idea really how to do it.

Maybe there´s already something easier inside Dreams features to achieve it? If not, any suggestion to do this easily?
