A Custom Vehicle option

How about adding at the bottom of the list of vehicles a “custom vehicle” option. Where a user can type in the batter size, DC charging speed, range, charger port type, efficiency, etc. This way those of us who have modified our stock EVs can still use ABRP. Because right now we have to pick a model from the list that “best fits” what our modified cars have but it doesn’t work as well if we could optimize the stats of the car with a custom option.

Thank you.
