Hiding battery on Harmony

I have my Harmony hooked up to a charger all the time, so I have no need to see battery or charging status. When I change the clock face settings to not show the battery, it still shows up though. It is only hidden when I disconnect the clock from power. This is precisely the opposite of what I want and what I consider intuitive.

I don’t care about battery when connected, but wouldn’t mind seeing the battery when I disconnect the clock and it is actually running off the battery.

Is there a way to hide the battery status when the clock is plugged in?
