Display Volts / Amps on D-180 Main Page

[Piper J3]

Is it possible to reconfigure the main screen on D-180 to show voltage and/or amps instead of manifold pressure?

Right now I have to go to a second screen to get electrical parameters. I prefer to have this information displayed in the primary EMS screen. With the RV-12 fixed pitch propellor manifold air pressure isn't of much value.

Thanks in advance...
