change external load-outs into internals

[gazpode_l]

Im currently skippering U-93, a ViiC style u-boat in 1941.

What I want to ask is that my boat carries two external stored torpedoes, one for'ad and the other aft.

I never get to use these because each time I need to bring these inside, we are in over 5 meter seas and practicly impossible for me to do so.

So what I am thinking is changing my game so that it reflects these are carried inside instead.

I've seen how I can change this but forgotten how.

Can anyone help me with this or do people think this is cheating - if so I won't do the change and just run without them in the future, keeping my weight of my boat down and thereby increasing mileage.

Ur thought's please
