Hi Folks,
I'm having a hard time figuring out how to add two types of items to a SysML IBD: Ports and Non-owned Items. I'm on EA 15.2v1555.
Please see the BDD below. Foo has a port and Bar has a port of its own, but since Bar is a specialization of Foo, then Bar actually has both ports. Additionally, Bar has a referfence association with Baz.

I'm trying to create an IBD for Bar that looks like the following, but I can't get it do do this in EA:

Instead, when I create the IBD, I can drag and drop Bar's owned items, including its port and its part onto the IBD by selecting the item under Bar in the Project Browser:

...the dragging and dropping it onto the IBD...

However, there seems to be no way to add to the IBD the port that Bar inherited from Foo or the aBaz, which is not owned by Bar (though Bar has a reference association with Baz). If I try to highlight the port under Foo and drag it, that doesn't work, and there is no way to find a Baz that I can drop onto the IBD as a reference.

Any help would be appreciated.
Thanks,
Miguel.
