The Duplicate an Item feature allows you to easily clone an existing Item including all questions, content, layout, and tags associated with that Item.
To duplicate an Item, open the existing Item template. With the Save button on the top right, there is a drop down arrow that will also allow you to duplicate the Item. The Item will be cloned and the new reference number will have "_duplicate" appended, which can be overwritten.
