A Check All button for students enrolled in Classes for recital.

We automatically opt in students for recital. It would be great if after each recital is finished, we can go back to the student page for students enrolled in classes and do a check all for students to opt them into recital. OR be able to Uncheck/unenroll students in recital participation so we can check them individually as they opt in to recital. In order to "reset" the recital particiaption, we have to go to each student's page individually and it takes an insane amount of time.
