Sync with local json task file

[JulienBrn]

Is your feature request related to a problem? Please describe.
I'm currently running label studio with a local storage source for keypoint labeling. I need to have additional metadata about the images that are being labeled, so I'm using the json format for tasks and I have switched off "Treat every bucket object as a source file" in my source storage.
The json file describing the tasks is always stored at the same specific path (that I could transform into a URL if necessary). Is there anyway to keep the annotations tasks and the json file in sync (when pressing the sync button in the UI) ?

Describe the solution you'd like
In source storage, be able to pass the path to a json file containing tasks. The sync button should update the annotation tasks using that json file (creating new ones, updating the metadata of old ones and perhaps deleting tasks). The merge should be done using the id field.
Buttons in the UI that modify the task (such as the delete task) should either not be usable in this case or should update the json file depending on some source storage configuration.

Hello,

Thank you for contacting Label Studio!

Currently, Label Studio does not support automatic syncing from a single JSON file stored in local storage

the actual behavior is as follows:

• When using the “Treat every bucket object as a source file” option enabled, Label Studio scans the storage to generate tasks from individual files.
• When that option is turned off and you’re relying on a JSON file, the system requires a manual import—the sync process does not merge or update tasks from the JSON file.

Nonetheless, I will happily forward your request to our Product team for further consideration, as we are constantly improving our product!

Let me know if you need further details or have additional questions.
