That's a good point perhaps if they were colour coded like the busses and tracks it would make life easier. I know that ever since I started colour coding things. White for Aux channels, Red and Orange from drums. Green for Synths. Blue for Vocals and Purple/Pink for instrument parts etc.
Or even just group them and separate them with a divider line by the type of routing assignment. I'm sure that's harder to implement than it sounds. Or even a secondary context menu which can be selected by hitting on a greater than symbol like >.
