You can add all kinds of content into an Outline:

• A Word, PDF or image file – Make sure the file is first saved to a shared location so that users will have access to in in a live Quote File.  If the file is not in a shared location (e.g. SharePoint, Cloud-Stored files, or a network location), your associates will not have access to the file if they try to generate the output. 
• Doc content from the Content Library  
• Bullets, sub-bullets, paragraphs and headings
