———————————————————————————
I would like to be able to manually change the suggested charging time at a specific charger. Say I'm planning a trip and I know that a certain charger is particularly cheap or even completely free to use and ABRP suggest that I charge there for some short amount of time, like 15 minutes. I would like to be able to tell ABRP that I would like to use that particular charger for a longer period of time, or until I've reached a certain percentage of charge. I can't see how to do that now. Also I don't see any way to tell ABRP to plan a route that explicitly includes a particular charger. That would also be helpful.
Thanks!
