Are Pinned Locations Searchable?

Hello Everyone,
I am having trouble sorting and filtering my observations after uploading with pinned location data. I would like to have personal project pages for all observations in specific pinned locations, but it seems I can only search and filter using recognized “Places”.

Is it possible to search and sort through my observations using my pinned location names? It seems like I am only able to filter using existing “Places”, despite the observations being listed with the pinned location name. This makes it very difficult to sort my observations since I am in the habit of using pinned locations during upload and then find myself unable to sort them once they are posted.

I have been dissuaded from creating a “Place” because the locations are small and intended for personal organization.

I have also considered using “Tags”. This does not seem ideal, but I would settle for it if I could edit multiple existing observations. Is that even possible?

Again, I am looking for a solution to help me create personal project pages for observations in custom locations without burdening the system by creating a “Place”. What are my options?

Thank you for reading! I hope that makes sense. I look forward to hearing your suggestions.

James
