S6 loudness metering?

I'm getting close to buying an S6, but I'm still trying to sort out what configuration to go with. I'm hoping to get rid of the 22" monitor I currently have off to the side of my workspace. It's mainly just for metering on my master bus for Dorrough meters and Isotope Insight for loudness compliance.



I don't see anything in the S6 documentation about what types of metering options are available for the display modules or the master module. Can anyone shed some light on this for me?
