 Comment 0: Hi @texanraj , I was wondering if you could expand on this some.

Where are you expecting to see these connections? How are you making these connections, can you provide some examples of configurations you are trying to visualize?
 Comment 1: Closing this out, but feel free to reopen with some more detail of what you're hoping to see.
