Show inherited attributes on entity

When I create a domain model entity and generalize it, I don't see the generalized entity attributes in the new entity. Which is fine if the entity I inherited from is in my domain model, but if it is from another domain model  (like a System.Image) I have to open another domain model to view the attributes on that entity.

Can you include these inherited attributes in the new enitity? As grayed out fields or something? That would make it easier to see which attributes the entity contains in total. I have defined duplicate attributes or similar attributes, because I didn't know they were already there.
