I'm brand new, here, so I apologize if I'm not using the search function correctly...

Is there a way to expand the number of selectable characters on the character selection screen? For instance, I have two different PSAs that I'd like to put over Link, but only one Link. So, in keeping with that example, would there be a way to have a link I could select from that screen with one move set, and a new character box (not sacrificing any of the other existing Chracter's selection boxes to make room for that one) that I could select with a link skin and a different PSA move set?
