Sub specific sounds?

[Capt Jack Harkness]

I'm guessing this is hardcoded, but is there any way to get submarine class-specific sounds? The main reason I'm asking is because of the diesel-to-electric switch over after dive...

On most of our boats in WWII this switch over never occurred because they were diesel-electric and the motors drove the sub 100% of the time, with the diesels charging the motors and batteries on the surface (thus they were typically called diesel generators). However, it would be unrealistic for the S-class boats to just paste the motor sounds over the engines and eliminate the temporary stalling of the props because they were direct-drive and did have to switch over from diesels to motors.

So I guess this mod would require an animation tweak as well, but would it be possible to do for each sub individually? If not, I'd settle for just the removal of the switch over animation and overlap motor sound on the engine sound for surface running (I don't use the S-class very often).
