Duplicate the router for the virtual users, change its name and transport (you need to write this to do what you want) and remove any side effects. Make sure the new router is just before the real router (routers are tried in order), add the "unseen" keyword.

This router and hence the specified transport will accept a copy of the message at the point it is tried (as you copied the acceptance conditions), but the original message will continue to the real virtual users router (because of the unseen keyword).

A good place to look at this in action is to look at the vacation router and transport.
