Different Calendar Views

 Is there any way to create different calendar views to the Moodle Calendar i.e. to perhaps create calendars based on year groups like below?

Grade 6 Assessment Calendar.

Grade 7 Assessment Calendar.

Grade 8 Assessment Calendar

I know one can filter events in the calendar by hiding site events or group events, etc - but is there any way to setup the calendar so that if a user clicks on the appropriate calendar link above, then they will see only assignments and events that pertain their respective groups.  Please advise

We are using Moodle 2.4 in a hosted environment
