Are you able to filter it to only species you haven’t observed? I have a quick save URL to specifically look for species I haven’t seen, and that’s kind of the goal I’m aiming for.
I was thinking a good alternative, is to add Great Plains locations for each state since ecological polygons can provide a lot of useful information over geopolitical polygons. Example being NM Great Plains, TX Great Plains, etc. If I import those all in within the week, I can just use the location id to fulfill my intentions.
