Model.Entity.Relations does have all of the information you need. It is just that the information is presented in a way that is not easy for you to
build the browseable list. However, it can be done.
I suggest that you create a utility or method that will do what you want it to do. Get all of the Entity Relations in your application by calling GetEntityRelations() and then step through each of the entity relations to build the browseable list that you want.
