Limit 1 per player or group

How could I limit automatically spawned building sites so 1 player (or better 1 team/group) can't have more than 1 monument with their TC?

Thanks

"The maximum number of locations that one player can summon (-1 - not limited)": -1,

Are you talking about this?

This option is already available in the config.

No, I'm talking about if monuments are spawned automatically (not summoned by player) on the map and player then comes and builds TC on more than 1 building location.

Basically, when you create them using "respawnsites" command
