ZombieSurvival disable ranks from joining certain arenas

My server which is based pretty much completely around ZombieSurvival it is starting to gain some more players and people who'd like to donate. My players who are thinking of donating would like to have donor specific maps. I have a map named temple with no capitals. First I tried '- -zs.join.temple' which didn't work and I thought if I did '- -zs.join' would still allow people to use signs to join the map but just didn't allow players to join maps at all. Does anybody know of how I can disable just those maps for certain ranks?
