Custom Model Data (Or other NBT) for CEM items

[el-piedras]

I know this must've been suggested to death but surprisingly I didn't find anything specifically for this:

The ability to choose exactly when and which CEM models will be used on CEM models. For example, the trident entity model can be edited with CEM, but doing so replaces every trident in the world, with no ability (To my knowledge) of changing that since it isn't a "real" entity in the world.

This could be done by setting a specific NBT tag such as CustomEntityModel:number, similar to how CustomModelData works, and a new list property in the model.jem file named similarly that only applies the model to entities or item entities with given tag.
