repeated authors in footnote handled differently than repeated authors in consecutive footnote

Currently you must treat repeated authors within the same footnote and consecutive footnotes the same (with the setting in ‘author lists’). I need to be able to treat them differently. I need to use the short form for repeated works in consecutive footnotes, but ‘Idem’ if works are by the same author within a footnote. I would like to see this functionality added to the product. You may see my Case #TS-01370626 for more details if interested. Thanks!
