A better practice may be to place the node close to the entrance and well-map all driveways and walkways.  Then routers should be able to make the most correct choice.  I would do that and if the router is still not behaving correctly, open a ticket with Magic Earth.  Note that many apps that do routing will have a significant delay between data changes and when it shows up in the app.  Putting the address node in the deliberately incorrect spot is bad practice for what I hope are obvious reasons.
