Composite Diagrams - Reuse Ports

[aljazjelen]

Hi everyone,

The problem I have can be trivial. Maybe its not even solvable. In any case, any help&tips are appreciated!

I have a diagram, where I show an overview of elements. Those elements have ports. Now I would like to create a child diagram, reuse the ports from the parent element and model the "interior" of the parent element. For example to show what is happening inside.
I modelled in such a way, as shown in pictures below:

Then I would like to use "compartment visibility feature" (or anyother proposal) to show the "Interior" of the child diagram on the initial/diagram. See below:

However, when I do that, the ports are shown twice, eventho the port is defined only once.

Is there a way, to show interrior of the element (so to show child diagram) and reuse the ports from the parent?

I hope my question was clear
Thanks!
