Northwestern has physicians across 8 sites and frequently has to check and uncheck sites in site filters. If they do not know the home site of a particular physician they have to manually check all sites. Please add a "select all" box to the site filters.

The physicians have requested a related ability to initially have all sites selected, then be able to unselect those they don't want searched. The search preferences should be stored as part of the user's preferences.
