Interactive route planning

On ZapMap you can select an option to route based on chargers on route. They show every charger within a distance from the route plan.

I was thinking, could you add an option that rather than selecting chargers for us, we can enter a start and end (plus waypoints) then click on chargers we want to use and have the system say what charge it thinks we would have (even negative to say you’ll need to stop before) when arriving?

Sometimes I found the auto planner makes weird routing decisions (like going miles out of the way), and I actually prefer to make my own choices as to where to charge.
