Changing the "Default" crew response?

[DeepSix]

Last career, the first time I got attacked by airplanes, I clicked "Dive to periscope depth" and also, unfortunately, clicked "make default" to make it the standard operating procedure. Ok, now, a totally new career, and I've come to hate that choice I made about S.O.P. - there are times when I want to crash dive, not just glide gently down to periscope depth. Heck, sometimes I want to shoot back, just for fun.

Aside from being somewhat puzzled (why does an option I chose last career still affect a new and different career?), is there a 1 or a 0 in a config file somewhere that I can change?

Thanks!
