Unity's 2D sprite editor doesn't allow placing bones in multiple sprites?

Question

Hello Stack OverFlow friends,

Please, sorry my pour english, and sorry for my newbie behavior in Unity, but I'll try to be as clear as possible:

I'm trying to create a 2D animation with bones, through unity's own sprite editor where everything goes well if I don't Slice the image... the bones act correctly on the different parts of the body.

But... I need this image in sprites.... because each part will be able to be changed in the game later..

soo, from that point forward, the bones no longer act on the other sprites!

What am I doing wrong?

Thanks!

unity ver. = 2022.3.7f1 and 2023.1.7f1
