Something like a Multicore Cable could greatly enhance a clear view in a Blueprint. What I mean in detail is something like and enhanced reroute node where you define more than one inputs/outputs just like in a macro so it can accept more than one cable. You could expand the node to see all the inputs/outputs to plug in the cables and you could collapse the node to make it look just like an existing reroute node. Just wild idea that crossed my mind 
It would make it hard to select one output.
Also you can already do that with structs.
But then you would need to mak a specifuic struct of every combination of value types that you want to ropute together.
Ideal would be if it would work just like the make/brake struct approach, but the editor creating these “transient” structs internally and transparent.
