Button or key request--decks awash

[Rockin Robbins]

Here's my crazy idea. I like to run around in the happy hunting ground of Nip aircraft with decks awash: keel depth 35ft. This way I keep running on diesel, I can use my radar and the splash keeps my lookouts cool in the hot sun. Wouldn't it be nice to have a button or key command to dive or ascend to 35 ft? Also, this depth might be different for different models of subs, so the same command should work for decks awash on all the different classes of submarines. That's my suggestion. I will now put on my helmet and you may all begin throwing rocks.
