Hmm. input value port assignments are not really included in the search, that is true, but that is also because they are not really variables (in the FlowCanvas sense of variables), neither are they nodes (which are included in the search). I could take a look at this possibility however, even though I can’t promise anything since that is a special case, meaning that you want to search for a value input port assignment, specifically only when a Unity Object is related. With that said, it’s been added to the TODO list for further consideration 🙂
Thanks!
