Automator - automatically copy files/folders when tagged a specific custom label
Check out Taggy Tagger.

It is a macOS menu bar app which automatically tags files and copies/moves files to a specified folder. Right now, it supports Dropbox, Box, GDrive and OneDrive as destinations (actually you can select any destination folder).

How does it work?


Select the folder that contains your files.
Enable copy/move action (Dropbox, Box, OneDrive or GDrive)
Select path to destination folder


From now on, everytime you add a file to the folder that you selected in step 1, it will add a tag and copy/move the file to the destination folder (step 3). Alternatively, perform the action for all files already sitting in the folder by pressing a button.

There is video how it works on the website as well.
