How to reorganize an S3-backed up library

Question

I have all of my pictures and videos in Backblaze S3, and local. The only organization currently is by year.I would like to make subfolders to group pictures/videos by event as well.Is there a way I can do this locally, and have the remote archive organization updated as well, without retransfering all of the files?

The backblaze backup software supposedly has dedupe detection which should help with renaming.
However you mentioned you're using Backblaze S3. I assume you mean you're using their S3-compatible B2 service, and you didn't really say if the software you're using to sync local to B2 is the backblaze software or something else, so it makes it a little difficult to help you.
If the object synced to B2 are keyed in a way that resembles folders, then like S3, to restructure you have to copy the file with a new name with the new folder structure you want.
You can avoid having to do this without retransferring from your machine by using API calls against B2.
