Different prefixes for all users

Hi Nick,
i love this great plugin.
This is what i need: i have four users and would love for each user to display different title before his name, i guess this sholud be done with
%prefix% tag, but when i do that prefix is the same for all users is there way to every user have different prefix?

Thanks !
