Retrieve Specialization over association

What I found in the modeler is the following situation:

I have Object → associated to generalization → has a specialization object that I want to retrieve

• If I want to retrieve the specialization over association, I need to use an Object type decision combined with a Cast
• If I use a microflow parameter input, I can directly (over that same association) retrieve the specialization.

I reckon this functionality should/could also be made available when retrieving over association, so:

Please make it possible to Retrieve a specialization over association.
