Change of how much the vehicle shall charge

I miss a function where I can decide how much I want the vehicle to be charged.
E.g. I am planning a longer route with two stays in hotels.
Both hotels has a charger, but when I add the hotels as waypoints, I cannot tell how much I charge the batteri at the waypoint.
To work around this problem, I have to create several separate route, which takes time and more difficult to get the overview.
