Styles and Formating / Numbering Help!

[stealth915]

I am trying to create an outline in Word 2003, and I want to have the
following:

1. Heading 1

1.1 Heading 2
1.1-1 Some Text

1.1.1 Heading 3
1.1.1-1 Some Text

1.1.1.1 Heading 4
1.1.1.1-1 Some Text

How would I set this up in the Styles and Formatting? I've set up an
"Outline Numbered" list, with level 4 being 1.1.1-1, but now how do i get my
Heading 4 to be in the format of "1.1.1.1"?

I guess, more specifically, I have an outline set up with headings that go
like this:

1. Heading 1
1.1 Heading 2
1.1.1 Heading 3

If I wanted to put text entries under the heading, that reference the
outline number, how can I do it without messing up the numbering of the
outline?

ex:
1. Heading 1
1-1 Some Text

1.1 Heading 2
1.1-1 Some Text
1.1-2 More Text

1.1.1 Heading 3
1.1.1-1 Some Text

2. Heading 1
etc.
