This has been requested before and it can't be done because you would need to save the database after each display/copy operation, or the data would be lost. This has greater potential for corruption during save and very poor performance over slow links.
It is also not possible to determine which user used the entry because there is only one password, which can be used by anyone.

If you want auditing there is a trigger example that may help.
