Move Animator to parent object

I took an asset from the asset store with some animation.

The animation expect the Animator to be put directly on the object that contains all the bones.

=> fbx (with animator) => bones

I would like instead to have a parent object, where I put the animator (and other component) so that I can do some manipulation from within the animation. so move to this instead

=> Root (components and animator) => fbx (without animator) => bones

problem is, by moving the animator up from one layer, all the animation breaks cause they can't find the bones

Is there a way to easily remap it so this ? they are just inside the child gameObject
