How do I create damage resistance for each part?

I want to give each part of the skeletal mesh detailed damage resistance. There are multiple bodies on one bone and I want to judge each one individually, but I don’t know how to do this.
I saw a way to set it using a physical material, but since that was already being used to determine the Niagara, I was unable to use this method.

Does anyone know a good way? Thanks in advance.
