how do i get a copy of a mail 'sent-on-behalf-of' in 'sent items' of the sender?

I am looking for a way to get a copy of a mail sent by person1 on-behalf-of person2 in the 'Sent items' folder of person2. Normally, a copy of a sent email is placed in the 'Sent items' folder of the sender. Is there a way to get a copy of the sent email in the 'Sent items' folder of the person, in whom name it's sent?

Example:
Person1 sends an email on-behalf-of Person2. Person2 need to see it in his 'Sent items'...


thx
