Model Reference with bus object

Hi,

So I used to work in Simulink R18a, and when you created a Model Reference from a subsystem that had buses as inputs or outputs, it would create its bus objects automatically. Now I'm working with R20a, and when I do that, instead it creates In/Out Bus Element ports and creates the whole bus structure, which in my opinion makes the model less clear and more complicated to modify if I have to add/remove a signal in a bus.

Is there any way of changing to how it used to work?
