Outline numbering doesn't work for Body Text

I have a legal document and I want every heading and paragraph numbered. Eg,

1 Heading One
1.1 Subheading one-point-one
1.1.1 A paragraph giving info relevant to subheading one-point-one
1.1.2 Another such paragraph
1.2 Subheading one-point-two
1.2.1 A paragraph giving info relevant to subheading one-point-two
etc

When the paragraph has a heading style, I can promote or demote the paragraph using Tab or the Increase / Decrease Indent buttons.

However, Body Text paragraphs show outline numbering, and also the buttons (and tab shortcut) do nothing for the hierarchy: they are fixed at 1.1.1 level (1.1.2, 1.1.3, etc)

I can work around by applying a heading style, getting all my paragraphs to the correct level in the hierarchy, and then applying Body Text style. But this ‘should’ be unnecessary.

Am I missing something?

Thanks.

PS Hitting “enter” at the end of the Body Text paragraph gives the next paragraph an outline numbering that is the next in the sequence, but again, it cannot be promoted or demoted.

How do you number your Body Text paragraphs? “Outline numbering” is a very special list. To avoid issues, it is protected against “easy” assignment to paragraphs.

Apparently, you want to include your Body Text paragraphs into the outline hierarchy, but these paragraphs will probably appear at various levels. Your example shows them at level 3, but is this always he case? If the answer id yes, use Heading 3 (and customise the style to make it look like Body Text) or replace Heading 3 by Body Text in Tools>Heading Numbering.

If the answer is no, the case is a bit more complicated by doable but you’ll lose the automatic association between level n and Heading n. The solution is to attach a custom list style to built-in Heading n and the same list style to Body Text. And you’ll need to manually promote each paragraph to its numbering level with Tab or Shift+Tab.0

Before I describe a solution, I’d like to have a look at what you did in a reduced sample document.
