Can I edit a pack after it has been created from an upload?

Yes. Creating a pack from an upload does not mean every detail is locked straight away. After the pack has been created, you can still review and update the pack details where editing is available. This is useful if you notice a product needs to be changed, a quantity needs to be updated, or a subject needs to be adjusted. The upload helps you get started faster, but you should still review the created pack before finalising it.
