From the service menu (3-dots at the end of the service line in your project), you can select the "Duplicate" option.
When you do, you'll see a modal that gives you the option of including the files in the new draft that is created.
A new draft for that service will be created within your project. The instructions, options and add-ons, reference materials, and quantity will be copied over, as well as the files you uploaded (or the links you provided for your source and finished files) if you choose this option.
Once the new draft is created, you'll be able to:
select a different editor or AI model.
change the quantity.
add or remove instructions or reference materials.
add or remove source files or the finished files destination.
This new draft is created within your current project, not in a new project. When you've finished configuring your draft, you'll finish the process by purchasing your order.
Important Notes:
A service cannot be moved from one project to another.
You can also copy the whole project (from the Actions menu button) but this will not include any of the files.
There is no way to duplicate a service and create a new project from that draft.
