Upload to Dropbox

I've setup my media library in Dropbox which is connected to my Plex Media Server using Plex Cloud. Currently setup selective sync and specified not to sync my Media folder to save space on my hard drive.

I was using Hazel to automate moving my Movies/TV Shows to the media folder, which would sync to the media server. Now that the media folders are no longer on my hard drive, I've had to set up a new folder with new Movies/TV Shows that haven't synced with this folder and upload the content through the Web UI to keep Plex up to date.

Does anyone know any workflows/Scripts/Apps/Automation tools that can monitor the file and upload the contents to a Dropbox folder that isn't synced to your device?

For a similar reason I have been looking at a tool called CloudMounter from Eltima. This allows you to connect cloud services, including Dropbox, as if they are external drives. I haven't tested with Hazel, but you should be able to use it to write to the un-synced drive.

There is also a service called CrossCloud (https://crosscloud.io/) that seems to do something similar.
