Currently, when you disguise an entity as another entity, the disguised entity plays the sounds of the original entity. I would like if there was a way to make it so disguised entities would play sounds of the entity's disguise, and not the entity itself.

If such a flag were to be implemented, you would be able to have e.g. a Wolf disguised as a Zombie, making sounds as if it were a Zombie (and not a Wolf).
