There are certain fields that aren't necessarily unique, like Student ID, but have the potential to be used as a unique field. It would be beneficial to have the ability to select a field, particularly fields like Student ID, Host ID, or SSN, and be able to check if any users share a value for this field, through a button or list of some kind, so they can be made unique if a duplicate is found. This can be useful for auditing fields that should be unique or that an organization wants to keep unique.
