[X3D-Public] Any way to get 'this' proto instance inside itself?

I need to create a ROUTE to/from 'this' proto instance's node. I know I 
can get at 'this' proto's node's fields with IS, but how would I 
construct a ROUTE on-the-fly?

More specific to my case: I have an external script that I need to ROUTE 
to/from proto instances, and I want the proto to create those routes.
