Are these mods possible?

I'm curious if it's possible to change subs depth with a toggle so they can be shallow (can be ground fired) to deep (could not be ground fired)

I'm also curious if we can make any unit fly with a toggle, including subs.

Thanks for any help!

all possible, wie ease even as the differs between shallow and deep water anyways and flying units do need to need anyways putting it behind a toggle or switch is not that hard.
