Great app, but needs tank defaults and a matching desktop app

Itd be nice if we were able to define defaults for tank size and pressure. Ive dived Al80s (3000 psi), Steel 100s (3442 psi) and twin steel 130s (3442 psi).
Id rather select from a list of three options instead of having to separately select tank material, size and max operating pressure for each logged dive.
I was only able to import less than a quarter of my total dives, a matching desktop app would certainly make it easier to get the rest of my dives onto my iPhone.
