Exclude a list on Identify page ("without_list_id")

Platform(s), such as mobile, website, API, other: Website

URLs (aka web addresses) of any pages, if relevant: identify and explore pages. Also, relevant thread: https://forum.inaturalist.org/t/exclusion-filters-exclude-taxa-entering-a-large-list-of-species/20643

Description of need:
Currently, there are many helpful URL modifiers that can be found here: https://forum.inaturalist.org/t/how-to-use-inaturalists-search-urls-wiki-part-1-of-2/63

As far as I can tell, there is no way to use these modifiers to exclude a list of taxa without chaining together something like this: &without_taxon_id=111111,222222,333333,444444… This, of course, can become cumbersome very quickly.

Feature request details:
I am requesting the addition of a new URL modifer: “&without_list_id=”. This would combine the functionality of “*&list_id=” and “&without_taxon_id=”.

I am currently attempting to learn how to id a large genus, Astragalus, in Colorado, and am doing so by going through research-grade observations in the identify page to practice. As I become confident with more species, it would be helpful to be able to add these taxa to a list and be able to easily exclude that list from the identify page, so I’m only looking at taxa I’m less confident with.

I’m sure there would be many other niche use cases for this feature.

Not the most consistent parameter naming, but you can do this with e.g. https://www.inaturalist.org/observations/identify?not_in_list_id=300. Beware it may not work for very large lists (>65k taxa), depending on the other parameters included in the search

Nice! That’s exactly what I’m looking for
