Show battery voltage with any battery instead of percentage/time?

[Jarek Zabczynski]

So I've been used to seeing voltage only my entire time with Red until I moved to DSMC2. Now I get percentage or time remaining on most of my batteries. I haven't particularly found it as accurate as just seeing my voltage. Is there anyway to see voltage on my batteries again? When I hold the power indicator and drag up I just see options for percentage or time remaining. I've looked through the menu and don't see it.
