Separating Buddypress groups on a multisite installion


I'm currently building a multisite network where I would like a Buddypress setup to be separate for each site. I have solved the user problem where each user has a different profile on each site, by adding - define( 'BP_ENABLE_MULTIBLOG', true ); - to my wp-config.php file. Though when it comes to groups no matter where I create a new group it shows up on every site. It is possible to separate Buddypress groups for each multisite site?

Thanks for your help,
