I don’t think there’s an easy way to search for such levels, maybe API can be used for that.
(For species it’s easier and you can do it with your new life list or https://forum.inaturalist.org/t/ever-wonder-what-you-havent-seen-in-your-area-before-here-you-go/11406 /there’s an ability to change “species” to other ranks, but it still will show you species from them/)
