Is it possible within Oracle EBS to determine if an attachment has been opened and what user opened

Hello -

I am posing this question even though I'm doubtful that it is possible.   We are changing a business process where we are requiring our employees to attach their receipts to expense reports and it's the supervisor's responsibility to review these receipts.  Our Audit department is asking if it is possible to know if an attachment as been opened and if it is also possible to determine who opened it.

Any help is greatly appreciated!

Thanks,
