There is an earlier feature request to separate
Wild versus NOT Wild (dump the Captive / Cultivated which causes endless confusion)
from
Needs ID versus - RG for Wild and a new CID for the Not Wild.
https://forum.inaturalist.org/t/make-captive-cultivated-not-automatically-no-id-needed/112
https://forum.inaturalist.org/t/rename-research-grade-discussion-and-polls/590
And also to split our valid obs in current Not Wild / Casual / Captive or Cultivated from the obs which are actually broken - Missing photo / audio / date / location.
I think your Isolated versus Not Isolated would be better covered by carefully edited Observation Fields? Or relevant notes from the observer.
