Cannot move/rename ancestral prim for SkelRoot

I am trying to follow the manual character setup of anim.people. As all people have then to be controlled by their SkelRoot name, renaming the root would be the only option to use multiple of the same model.

When trying to rename the prim or move it with the API, I get the error “Cannot move/rename ancestral prim”.

But if I duplicate the SkelRoot first and then just delete the old one, I can rename them.
Is there an easier way to control multiple of the same models using the manual setup of anim.people/ a way to rename the SkelRoot?
