Demographics Form Required Fields

Is there a way to set ALL of the fields (answers) on the Demographic Form to be REQUIRED?  Especially those fields that are populating CMS forms for insurance claim submission, and necessary to file claims.

Also, clients update their demographics information directly through their login portal?--- It would be helpful to have those updates/edits by the client pended while the SP system notifies the administrator (similar to that of a secure message) via email of those changes.  Then suggested updates from client can be acknowledged, reviewed and accepted into the record.
