Descent Mk2i screen config

Hi guys,
I am trying a Mk2i and have dived with my Teric normally, so I am trying to configure the screen with the following data:
Temp
GTR - Gas time remaining
Pressure

Then of course NDL, dive time, O2 %, depth

The primary screen on the Mk2i doesnt allow too much config, it will give me a few fields to configure but not that many. I can configure a custom screen but that has more fields that I need and I cannot do air pressure.

Am i missing something? My teric had a config as follows:
Depth
GTR Pressure
Temp NDL
Dive time

With such a fantastic screen (and a nice size), it is a pity I cannot do more customisation.

Am I missing something?

Thanks,
Nick
