Outlook 2011: Preserving original sender, subject and date of attached emails

I have a thousand emails that were forwarded to me by the same individual. For example, jane forwarded me 25 emails from jim as attachments in a single email, each attachment/message with a different subject and different date.  When I open each attachment, I see the original message:  from jim, to jane.  I desire to save this (and every other) message in my inbox or local folder as coming from jim, so that it archives correctly by sender, date and subject. Solutions would be greatly appreciated.  Thanks in advance.
