Switching from Grid charging to a Schedule solar only charge

I have an E2 charger which is over 12 months old. When charging from the grid using “Charge Now” App option, if I want to stop charging from the grid, I press the “Stop”. To then get the E2 to charge from a schedule setup to use only solar, I have to physically go to the car remove the charging plug and reinsert it to then utilise solar. Can and should I be able to do the same from the app without needing to remove the plug?
