I have a very lengthy word document that currently has Heading 1 as a numbered list, there are 8 of those. Below each Heading 1 I have more headings going down as far as Heading 5. I need to insert a new Heading 1 in two places in the document, one near the top and one about half-way through the doc. Once I insert those two new Heading 1 sections I want everything between the first one and the second one to fall under Heading 1. In other words all of the current Heading 1 things will become Heading 2, the Heading 3's will become Heading 4 and so on. Once I get to the second new Heading 1 I want the same thing to happen there. Is there an easy way to do this without manually selecting each and every heading and changing the style from, for instance Heading 1 to Heading 2, or 2 to 3, and 3 to 4, and so on?
