Why can't I enter negative charging KW for a destination

I used to enter negative KW charging at some destinations to account for normal energy losses that occurs when the car is not in use. I also used it when camping overnight in car - the car uses a few kilowatts per hour to run the HVAC. Now there is no way to account for energy losses at a destination. Am I misssing something? Is there a better way to account for energy losses that occur at a destination? These losses come from sentry mode, cabin overheat protection, running the HVAC and other places, but now I can’t estimate those losses and can’t properly plan long and complex trips. We recently did a 6000 mile trip across the country and found this feature invaluable to properly estimate energy losses and charging.
