To repeat again, you can't do anything about supplementals. They can not be "recovered". What you can do is have both a normal listing and a supplemental listing for the same URL. That has always been easy to do, especially for sites without dupe content issues. Millions of pages that have normal listings also have supplemental listings lurking in the shadows which appear if a normal page drops out of the index for some reason.
