We have several users with access to Reports and they inadvertently change the canned/system reports.  Is there a way to actually lock those reports so the users/technicians cannot change them and are forced to save them with a different name?  I know it is a training issue but it is very easy to think you're modifying a report that you've renamed but you're actually modifying the base report.

I see a lock icon next to them which shows them as Public but not sure how to make them Private, if even possible (I know it's a different issue but just curious).

Thanks.
