It's still text, but the right text with the right material.

I repeat myself, the information must be present twice in your part, materials of the multi-body part and materials of the body(s)
- Coin Ownership

- Body Ownership

These two properties are identical, but one is applied for each body, the other for the entire part, without any detail of the bodies.
However, this material property is both recognized in the same way by your nomenclature
