How can I make a Team hidden?

I am trying to make the team, "Undecided", hidden from other teams on the leaderboard. So say I was on Red Team, I could not see the Undecided team. But if I was on Undecided team, I could see all teams. Is there a way to do this?

I don't think it's possible to hide only one team, but you can't hide the whole leaderboard/player list: http://wiki.roblox.com/index.php?title=SetCoreGuiEnabled

game.StarterGui:SetCoreGuiEnabled("PlayerList ", false)
