I want to copy style data for built in headings, such that the Heading 5
takes on the attributes of Heading 4, Heading 4 becomes Heading 3, etc. until
I can define a new Heading 1. If I select a paragraph with style Heading 4,
then in the Styles and Formatting window select "Update to Match Selection"
for Heading 5, Heading 5 will take on the required attributes, but only
because it is redefined to be "Heading 4 + Level 5". If I now update Heading
4, Heading 5 will change accordingly, which is not what I want. How do I
break the link between the headings without printing out and re-entering all
the formatting?
