How do I add a non-required supercharger stop to an existing navigation route? Of course, I can set the navigation to go to the supercharger, and then set it to my final destination when supercharging is complete. But is there a way to request the final destination and tell it to add the supercharger stop along the way? Again, this is for a non-required stop. I can make it from home to final destination without stopping. But as there are no superchargers where I am going, I want to arrive with as much range as possible, potentially returning to that same supercharger on the way back.
