How do you change uboat availability?

[Highbury]

Hello all,

To clarify what I am trying to ask.. I would like to be able to change the availability of the uboats, not only the Flotilla but also the year. So say, for example.. you can sail out of Kiel on Sept. 1st 39 in a XXI.

The reason I ask is my brother and I often do 'competitive careers'. For example we will both start on the same date, in the same boat. See who lives longest, accumulates more tonnage, renown etc. We have done alot of these with the realistic configuration and thought it would be fun to try a few far fetched ones.

I realize that typing instructions for such a thing can take just as long as writing a mod for it yourself, but if someone can point me to a tutorial or something it would be much appreciated. I checked the sticky post but didn't find a tut for what I am asking.

*Edit - Also, I don't expect this for all the late war torps etc, we can use them as they come out. Just anything that would cause a conflict. Conning towers, guns and ammo that are not generic from early war etc.
