Adding Commander abilities on the American Side?

[Charles Darwin]

OK I did a search of these forums and all knowing google and couldnt find anything dealing with what Im wondering

Is there a mod or a way to give American sub captains abilities like those of the german campaign?

I cant imagine this would be a real difficult prospect so Im sure its been done, but then I dont know much about modding so I could way off and itd require a huge effort

So just wondering if there is such a mod if someone could point me in it's general direction
