Hi, garlapati

Yes, this is possible. You can try the following:

Highlight the first group of lines you want to number, say from 1-90. Select "Format" and "Bullets and Numbering." Go to the "Numbered" tab in the "Bullets and Numbering" dialog box, select a numbering style and click "OK."

Highlight the next group of lines that will be numbered differently, say from 1-95 in the same document. Reopen the "Bullets and Numbering" dialog box. Then click the "Restart numbering" option and press "OK."

You can repeat this process as often as necessary.

Hope this helps!
