Our regular season just ended and All Star's is here now. I'm trying to add a new league but I wanted to see if there was a way to add players from the regular season and perhaps still use there hit locations etc?

Players, games and teams can all be assigned to multiples leagues. I personally don't bother assigning players to leagues, only games and my main team, but many people do. If you want to view player hit charts while scoring, just make sure that all leagues is checked while you are scoring the games.
