[Feature] API Scan External Library sub path or single file

The feature

First, thank you all for the amazing work on Immich!

I utilize an automated processes for managing photos throughout different apps and mainly use Immich for consumption of already tagged, structured photos which in turn means I rely exclusively on external libraries. These libraries are stored on bind-mounted CIFS shares so I will never be able to use native file-watchers in Immich.

I would like to have the ability to tell Immich that a file has been added or updated in the external library and request Immich to add it or update it in case it already exists, rather than rescanning the whole library for modified files.

Would it be possible to add an option for the /library/:id/scan API to scan only a specific subfolder within the defined external library path and/or a single file?

Thanks again
