After you have created some 'Export Document' folders, you can click to duplicate any folder to eliminate data re-entry.
You can duplicate folders in 2 ways:
Option 1 - Duplicate when inside a folder
When inside a 'Export Docs' folder, on the right of the screen, click 'More' then 'Duplicate'.
Option 2 - Duplicate when in table view
When viewing your list of folders, select the folder you want to copy, then click 'Duplicate' then give the new shipment a reference number. All data will be instantly copied to a new folder!
