There isn't enough explanation as to how the "order" works when creating or editing fields. A simple drag and move for fields would work better. To be able to add the same newly create fields on the summary tab to another workflow tab e.g. creating a registered office address for the summary tab, should be able to take that same field and add it to the annual return tab (confirmation statement tab). If the information in the field on the summary tab has been altered, the same field holding the same information on another tab should be automatically updated.
