Working with the new sections you can create new areas to define files like Artwork, Original, etc. Once enabled in module administration and configured in categorization, you can start using it. The new section is located on the top tabs and at the beginning having no data included.
Add files from create button (types digital or separated) to create the new files. The concept is the same when importing designs. Make sure to use the check box "Move to:..." to assign it to the new section. Else, it will be created as a new design. Once created you can edit, print, or share the file.
If you need to decide that this file should become a part of the design section and move to other designs, from the edit option, click on the remove action and it will be removed from the new section and added to all other designs.
