Synology uploaded in year/month folders, I did not want that, can the photos be removed from the year/month folders

The year/month folders were created by synology during the upload into photos. I initally uploaed into personal and then moved to shared. I had 1000 photos that synology won’t move from personal to shared - I think it believes they are duplicates. Some of them are not duplicates though the file names might be the same due to different camera source (e.g. img_999) but photos are very different. Some of them are duplicates. I want to compare file names and with photos but I can’t because (unless I do two searches for each name…) they are all locked in year/month folders. With the photos in year/month folder I can’t work with files. How can I remove them from that structure?
