Assuming this is Ruby:

     header = "Category: dummy\n"
     document.sub!(/^(?![A-Za-z0-9]+:)/, header)

That should insert the header below the last header line, or top of  
file if no headers.

For bonus points you might want to insert an additional blank line,  
when there were no preexisting headers.
