Please add ability to manually and quickly adjust the battery level on the car UI ?!

hi there , my electric avenger does not work with any OBD dongle ( tried 2 and the car goes in tilt after like 2-3 minutes ), therefore for long trips i have to manually adjust the battery level as i go, but in order to do it i have grab my phone because on the car’s screen UI there is no quick way to ± the battery (currently require 4-5 clicks to arrive to the menu to do it (than you have to get out) therefore i was hoping you can add an onscreen quick shortcut for it (maybe by clicking the battery level opens the + - buttons ?))

possible ?

thanks !
