I have a main library and am planning to create a temporary folder for images and videos required for my immediate project. I will use tags to organize these files and eventually move them to the main library. I'm considering this approach since there isn't currently a way to segregate or group files based on date, type, or folder structure.

Questions:

1. What potential issues might I encounter when merging the libraries?
2. Is there a script available to handle this process? I don't see any merge option in version 9.4.2 Alpha.
3. If I need to merge manually, what elements in the JSON file should I pay attention to for successful data migration?
