GL-E750 OLED Battery Status

The battery status appears to only be available on the Main Info screen.
Is there a way to add the battery status to the other info screens?
I turned off the Main Info screen, but since there are no LEDs, it is kind of a pain to shut down the unit completely to see the charge % if you want to see where the battery is at any given moment.

I just wanted to bump this to the top.
