A collection project would work. But maybe this could work too, depending on what you want to use it for: all observations of family syrphidae, identified by you: https://www.inaturalist.org/observations?ident_user_id=sbushes&taxon_id=49995
You can edit the URL with different users and taxa. You’d have to find the taxon IDs for the taxon you’re interested in. You’ll find the taxon ID in the URL of the taxon page, in the case of the hover flies it’s this:
https://www.inaturalist.org/taxa/49995-Syrphidae
^^^^^edit: well huh, @pisum was faster. So let me save face by adding that this thread is helpful for things you can do with URLs: https://forum.inaturalist.org/t/how-to-use-inaturalists-search-urls-wiki/63
