How to define a sidebar to a 'Group' in buddypress

Hi,

I have 21 groups in my buddypress site. The theme only allows me to set one sidebar for all groups (mikmag theme). The site is a football community and each group is effectively a EPL team (liverpool/Man Utd etc). Each needs its own stats and club related info. How can i assign a named sidebar to each group page? or is there a plugin that will do this?

Site is 'ynfa.net' if you would like to log in to look.

Many thanks
