You need to be careful when modifying a LEAP templates, because if LEAP later changes the templates to comply with legislation, you may not get these updates.
Edit an existing template - This is recommended in the scenario where a template exists, but it does not quite fit your style, and you are happy to overwrite the version in LEAP. The benefit of editing the template is that you retain the full history of the original template and a notification is given when LEAP updates the template, allowing you to incorporate the changes into your version.
Duplicate an existing template - Use this when the document is similar to an existing template, as in the above example, but the original is still relevant in some circumstances. The outcome of duplicating a template is two identical templates. You then edit the duplicate, leaving the original intact. It is essential to understand that Update Notifications will no longer be displayed on the duplicate when a change is made by LEAP.
