expiry override and data feed markers

would it be possible to provide markers/flags on a record to show which feeds have provided data to it? this would be handy when troubleshooting data shown.

would it be possible to override an expiry date when requesting a card? this would be useful when a member is continuing beyong when their uoc chris entry or camsis entry marked them for leaving but they are continuing elsewhere to reduce loss of service in the 'handover'.
