Confidential Attachment automatically saved to a candidate from Contact/Reference

Content

Is there a way to have a confidential attachment (letter of recommendation) from a contact/reference that gets saved automatically to the candidate profile?  The candidate will provide the email address of the contact/reference and in turn we want to be able to send and email to that individual with instructions on submitting this confidential attachment (letter of recommendation) on behalf of the candidate. 

Is this doable or has anyone done this?

Thanks,

Peter
