Is there a code meaning “Doesn’t have Field X”, analogous to Not_in_Project etc?
I need to add Fields to a few thousand observations, using each of about 40 Fields, adding each to about 50-100 observations. I need to find which observations do not yet have the Field. I planned to search in Edit Observations for all my obs within a Place - or Collection Project, either would work - excluding those obs that already have the Field.
I planned to bulk-add the Field with the Value “Indeterminate” and adjust the Values in another operation, or one by one over time.
I can’t add the Field to all the Obs in a Place because then I would lose all the Field Values of those that already have the Field.
