How to include header row in export settings?

Hi. I'm trying to export a taglist using the following string:
%_covers%;%_extension%;%_filename_ext%;%YEAR%;%ARTIST%;%ALBUMARTIST%;%TITLE%;%GENRE%;%GROUPING%;%CONTENTGROUP%;%COMMENT%;%ALBUM%;%MIXARTIST%;%COMPOSER%;%PUBLISHER%;%CONDUCTOR%;%BPM%;%INITIALKEY%;%_bitrate%;%_video_bitrate%;%_video_width%;%_video_height%;%_length%;%_file_size_bytes%;%_file_create_date%;%_path%;

This works just great except the resultant file has no header row. I tried using he following code which kinda worked, but it placed a header row before every track in the list.

Cover;Filename;Artist;Title;Genre;Grouping;ContentGroup;Publisher;Conductor;Comment;Year;BPM;Key;Album;CreatedDate;Extension;FileSizeBytes;Length;Width;Height;Bitrate
%_covers%;%_path%;%ARTIST%;%TITLE%;%GENRE%;%GROUPING%;%CONTENTGROUP%;%PUBLISHER%;%CONDUCTOR%;%COMMENT%;%YEAR%;%BPM%;%INITIALKEY%;%ALBUM%;%_file_create_date%;%_extension%;%_file_size_bytes%;%_length%;%_video_width%;%_video_height%;%_video_bitrate%;

What do I need to add, remove or do in order to export a file with a single header row? I've tried searching but can't find anything. Thanks.

Post withdrawn, the suggestion does not apply to Mac

See this thread for more context.

Have a look at the documentation:

It says that you get 1 line per file. So there is no way to get a single line as a starter.
Perhaps you could add
$if($eql(%_counter%,1),'Cover;Filename;Artist;Title;Genre;Grouping;ContentGroup;Publisher;Conductor;Comment;Year;BPM;Key;Album;CreatedDate;Extension;FileSizeBytes;Length;Width;Height;Bitrate'$char(13)$char(10),)
to get a line only for the first file.
