Plugin Help Creating Multiple PaidRanks Ladders

I am currently working on a prison server and using the plugins PaidRanks and GroupManager. I am having trouble creating multiple rank ladders in PaidRanks. We have the ranks going progressively from A1 - A5 but we want to make HelperA1 - HelperA5 etc. My rankprices file is here- http://pastebin.com/Rr9ywNUa Let me know if you have any idea of how to do this . P.S. I will not be wanting to switch plugins (PEX)/(Rankup Plugins) Thanks!
