In Referral Maintenance, add an "Archive" button that will remove the selected source(s) from the active database. Under the search field, add a check box "Include Archived Sources" so that these can still be viewed if necessary (similar to searching archived patients from Family File Select Patient window). Make these archived referral sources their own category in eDex.
Thank you for the recommendation, we are always looking for ways to improve the product. we will consider this for a potential future release.
