customizing the dive screens, several data fields are missing?

I can add a custom Dive display (not sure what they really are called) and i can change the fields, so far great but there are many options missing (or maybe I am doing it wrong).

This is what I want but ,,

left gauge = N2 (perfect I can select that)

right gauge = Descent (not available in the list of options)

top row = Transmitter Pressure (not available in the list of options)

first row left = TTS (not available in the list of options)

first row right  = ATR (not available in the list of options)

second row left = Breathing Gas (not available in the list of options)

second row right = Battery (I have not looked)

the bottom default fields (perfect)

Ok, not a big deal as all the info is available but spread out over 3 screens and I was thinking since I can customize I can get it all in one spot, but I need help on how to do this.

So far my thoughts on the MK2i, it's really really good! I have some minor gripes but they really are minor, and I have not dove on it yet.
