Plan with cheapest price

I do like the app, and use it a lit. the route planner is frustrating. there should be a setting to plan a route using the cheapest ev point depending on the amount of time we are willing to stop. for example, I would much prefer to stop at Gloucester services for 20 minutes pay less for electric than than take a different route paying a lot more. sometimes it has even stopped me twice for a 7 minute top up at 15p a kwh more than somewhere else.
