Being able to pin a route in ridewithgps and load it to the karoo2 without the need for a wifi connection

I think that the Karoo 2 software need to be able to load routes from ridewithgps without the need for a wifi connection.  Route data is not that large and should be able to be transferred via bluetooth connection from your phones data plan.  I feel the same for loading the ride after completion to the dashboard but that is not as important to me.  I would like to understand why this is not part of the software design.  Is it a battery drain issue for this feature?
