Vega Admin - Allow systemwide closure date with adjustments
When setting up closure dates, it would be helpful to offer an option to setup a systemwide closure date (may be adjusted for each location).
As a single library system, we only occasionally close an individual location; most closures would apply to all locations.
Some closures may be need to be adjusted, such as a systemwide closure for a hurricane and turn off each location's closure as we reopen the buildings.
