Robo-Recital - Just update classes/acts in a Recital

It would be awesome to have the option to "update" classes/acts participating in a particular show instead of dropping in every class each time you have to make a change to a show in Robo-Recital. i.e. add this "update" option to the 2 choices that are already there - Include all of my active recital classes. Just use the recital classes I assigned to this event.
