This goes back to a previous pain point and that being the visual connection between a link-call node and its corresponding link-in node.
Link-in and Link-out are visually linked and it's easy to navigate between the two, this is unfortunately not the case with link call nodes. And this is a pain point for me so I came up with a !!hack!! solution using green dots:
This is not the way it should be done but I needed something now and that was the simplest thing I could think of. The green dot on the link-in node brings the clickee back to the original link-call node (i.e. the first green dot clicked). Also, to remove the green dots, switch between flow tabs.
Hope it helps.
