Work with the copy feature
To copy an element, open the detail page of an Element you want to duplicate. Above the right sidebar, you will find the Copy feature between the Timeline and Edit icons.
Clicking on the Copy icon triggers a popup that double-checks if you really want to copy the Element.
When sure, click on Copy and you will be redirected to the create-form of the element, with all the relevant fields filled in. You will be able to add or edit any information and save the copy of the element afterward.
