Allow 'Section Filters' to update when sections are added
Currently, the site director is the only person who can turn on section filters within the calendar. If a subsite director adds a section to their site, the site director needs to go into filter options and check the box next to this new section for the calendar to be filtered. This is very tedious, particularly because site directors do not typically know when a subsite director adds a section. It would be helpful if the "select all" box can apply to all sections on a site -- even if the section has yet to be created. If the site director checks "select all" for each subsite, and new sections automatically are checked when added, then the site director would not have to worry about this again.
