Filter by "Date Added" to a Traditional Project

URLs (aka web addresses) of any pages, if relevant: N/A

Description of need:
Ability to filter by date an observation was added to a Traditional Project (not “Added to iNat”).

Feature request details:
At the moment, you can only filter by date observed or date added to iNaturalist. That is sufficient in most scenarios, but it’s challenging if project data is being collected and curated for new submissions on a regular basis. If we were able to filter for, for example, all observations added to a traditional project in June 2025, we could export only those observations and curate/sort the relevant data. At the moment, the only way to filter new additions is by performing VLOOKUPs. This approach will become unmanageable once we have thousands of observations within a project.

if that’s how you’re handling the problem right now, it would also be possible to set up a dummy user for the project, and use that user to mark observations as reviewed. then you could export only observations not reviewed by that user.

depending on what you’re trying to do by exporting those observations (for example, if you’re just trying to make sure all observations added to the project get an ID by one of the curators), you might also be able to use the pcid=true/false parameter (in conjunction with project_id), which can help you filter for observations with identifications (or without identifications) by project curators.

Thanks, interesting solutions I haven’t thought of, will see if I can use them. The collected data actually gets published every few years, so we need all the observation fields when exporting and what not. It’s just tricky sifting through hundreds of old ones to find new ones. I like marking observations as reviewed idea though.
