subscribe to specific group or individual user events?

Is there a way to set up the events plus plugin so that users can subscribe to certain calendars posted by certain groups or users on a multisite? This way a user could subscribe only to the calendars that are of interest and see new events hit their feed only from these groups or individuals they are subscribed to. For example, this might allow a user to see only five groups events out of 50 on the multisite.
