You’re welcome.
When moving from analog world to digital world I had a bit of a time grokking “virtual cabling”. Now I no longer think of it as “routing”, but rather “assigning”. Yes, it is routing, but you do it by assignment. Maybe a semantic difference, but words/terms do carry different baggage.
Task-oriented addenda to the manual would be a help, but you can always access the user base as you have done. In my case it took wrestling matches with the first five or six issues such as yours to get a feel for the topography inside the machine. Now I find it easier to know what to look for and where it might be.
