Pressure Groups on Wisdom

I just started diving and learned to use the tables to plan a dive. Recently I bought the Sherwood Wisdom diver computer which is great, but I find it slightly unnerving not to know my pressure group during the surface interval. As you know the Wisdom has a bar graph that moves through green, yellow and into red to indicate your nitrogen saturation level. I use the simulator to plan multi level dives, but I'd still love to know my pressure group. Has Sherwood ever thought of having a graphic for this (it wouldn't be very hard to design, the info is right in there any way!)

What a difference a day can make! I've done several hours of research since the above post and I know why there is no "pressure group" display in a dive computer other than a graph showing nitogen loading.

you can plan out the dive with a padi wheel for multi level and it will give you pg's ..use the computer also to keep track of things,use the computer also as a timer to follow your plan..If the computer craps out you can continue diving thru the day knowing what pg you are in..
