Role Scoper and Cimy

Hey,

Love the plugin, am working on a site that we are creating user roles and i want to place these roles as a drop down where when user registers they select the role they want on the site, how do i make it so that i have these roles available in the settings section as a drop down option in cimy user plugin (settings)
