Nested Outline

We're trying to craft a protocols manual. Is it possible in Zoho Docs to apply a nested outline to a document, i.e.
1 TOP LEVEL TITLE
      1.1 Next Level Title
            1.1.1. Third Level Title
                  Text text text text text text
            1.1.2. Another Title
                  Text text text text text text
      1.2 Next Level Title
2 NEXT MAJOR HEADING
