Friend Captain Suggestion

There should really be a way to just set what you want your friend captain to be without having to switch it around all the time. I like using Arlong for farming because he's very fast in my opinion, but I prefer to let people use my Vivi since she's more popular as a helper captain right now. Having to make that change every time I log off is annoying.

Seems like an easy addition to the game that would be a very nice and efficient feature.
