The web app enables you to import fields from one document/template into a new one, potentially saving you tons of time!
There are times when you’ve created the perfect template, including all of the fields that you need, but then something has to change in the document. Rather than redo all of that work, you can use the Import Fields option to bring all of those fields into your updated document.
NOTE: fields will be placed in the exact same place on the exact same numbered page as the originating document. This method is best when uploading a slight variation of the same document (editing customer information, or adding some text, for example).
