The best you could probably do is to go back and delete undesired recoords
at the end of the day because if it is as you said, they've already put the
information into the database.

the table to indicate when the record was added.

Nope, it doesn't --  at least to me :-)

How about some table structures and some more information,  I'm just not
exactly sure what you'd like to do..
