I agree that piano players see it as a Grand Staff, not two staves with special decoration. That said, no notation package I'm aware of treats it that way.
a couple of well-known Bach examples are attached, which I simply do not think NWC can reproduce.
Think again. The first example is attached. The second is well within the abilities of a dozen members here. I'll leave an example up to one of them 
All of this is going to become much easier in NWC 2.75
