Number unnumbered headings in TOC in Word 2010

Number unnumbered headings in TOC in Word 2010

I have a word document with a generated TOC for my headings (which are numbered). So far so good. Everything works. Now I have another document, which I have to "inline" into document number 1, so I copy and pasted and everythings still OK. My problem is, that I want to have the heading of the inline document unnumbered in the text, but appear with a number in my TOC.
Is that at all possible, appart from manual correction?
Example:
TOC
1   Chapter 1
1.1 Chapter 1.1
2.  Chapter 2
2.1 Inline Doc1 Title
2.2 Inline Doc2 Title
...


Text:
1 Chapter 1
...
...

1.1 Chapter 1.1
...
...

2. Chapter 2
...
Inline Doc1 Title
<inline doc text>

Inline Doc2 Title
<inline doc text>

....
