When Submitting a Request, ability to "populate or copy request from" old request

It would be nice if when submitting a request through any request queue, a user could select a "copy request from" option and then find an old issue or project, then this information would feed into the new form (as long as the fields were the same). This would at least give a head start on some of the huge forms our requestors have to fill out. OR, if they could go to an old issue/project and there was an option there to "Submit request from" then they could select the appropriate queue (that way the routing would work as designed). If the fields would just go blank if they do not exist anymore, that would prevent issues with custom form changes. I know this is probably a long shot, but I get requests for it frequently.
