Out of the box, InDesign already can do a fair lot, and some of the lacking features – simple or otherwise – can be implemented with basic workarounds – occasionally with the help of a script. However, placement, divison, and other lay-out of InDesign’s native footnotes are not that easy mimicked and the only way around that is a custom replacement of the entire footnote system. The Footnote features have not seen any change at all since their first implemention: CS2. I dare not look up the exact date of its release.
If you believe this would be a useful addition (and I tend to agree; why not?), suggest it at the Feature Request forum: https://indesign.uservoice.com/forums/601021-adobe-indesign-feature-requests
Make sure to browse related existing features, so if there is one that covers your idea and has many upvotes, you could vote for that instead of adding another new 1-vote only suggestion. There are too many of these already.
