Changing the routing is extensively described in the User Manual, and can also be done with the Routing utility. It is not the simplest thing, but most people can understand it with a bit of work.
If you find it impossible to understand, I'll have to ask you to draw out what you are trying to do (words are no help here) and email it or post it to support@eventide.com, marked for my attention.
Please try working with the User Manual first – it will sav us both time.
