Replying to myself (please remove if that is not allowed), these are the categories of the Casual section that could be broken down usefully in different IDing scenarios if a url could be built that excluded or includes the flag info. If even one more of them were broken out along with the Cultivated, that would be a good extra sieve. Preferred first choice to exclude from my perspective: Unknown place or date.
-Unknown place and/or date
-Cultivated (fixed, see thread)
-marked date and/or location Not Accurate
-marked No/No recent evidence of organism
-marked Can’t be improved
-Unlabeled records by users who have opted out of Community ID
