Have an "active" button for each individual season.

Having an "active" button to be checked and unchecked to display only the active seasons on the Ipad Class Manager prior to the season start date. For instance when setting up a new future season, teachers are able to see the classes that are assigned to them when you don't necessarily want them to be displayed yet. This way, you wouldn't have to go in to each class and uncheck the "active" button.
