Is it possible to control a Nested Family Type with A type parameter in the Host family? For Example I have a Water Closet Family. Each part of the family (seat valve china) is a separate nested family with multiple types. I would like to control what nested family type is being used by the host family type. Example I have a Flush Valve Family one type Manual flush, the other Sensor operated nested in my main Water Closet Family. I want to be able to control what type flush valve is used in my water closet family type parameters.
