Allow admin to select and edit multiple course reserves at once. It would be helpful to be able to select several courses at once to make active, for example, rather than individually editing each course to make it active.
In addition to 'enable'/'disable', 'export' (for downloading or printing entire lists) and 'export/print list of selected' (for a list of all active courses) would be helpful actions to be able to apply to a selected group of course reserves.
