Hi
Dear T W I said not to waste her time in copy control just because of this specific issue because it can't be rectified or fulfilled with copy control settings. For resolving this issue she will be wasting her time in copy control but you are right that we always learn something new while doing some R&D but what if she is not looking for learning something new but just to meeting her requirement. May be her business is suffering due to this issue and she have to get this done ASAP so she will prefer to resolve this at her earliest and she can explore and learn new things afterwards 
Thank$
