Copy Flows are configured in the GN4 system. There is a GN4 configurable User/User group tab named Copy Flows. This lists the available folder movement for content when the appropriate button is accessed.

In the screenshot example above, the Start copy flow function will move the content from its current location folder to the /Editorial/For Subbing folder. The Send Back copy flow function will move the content from the /editorial for subbing folder to the /Editorial/Returned back from Subbing folder and the Send On function will move the content from the /Editorial/Returned back from Subbing folder to the /Editorial/For Subbing folder.

For additional detail on Copy Flow configuration see Configuring Copy Flow Paths (folders, tasks/events).
