Open a document in the document editor. Under the “Document” settings tab, under “Document settings” you will find a property called “Fold setting” this allows you to select a folding setting for this document.
When the fold setting is one for composed documents you will need to specify the "Document Identifier" so the document gets assigned to the right location in the final composed folding
