Is there any way to set a Page Break?

Hi, I've tried to use the same format as PHPExcel:

$writer->getActiveSheet()->setBreak( 'A15', PHPExcel_Worksheet::BREAK_ROW );

but then I realized there's no "getActiveSheet" neither "setBreak" code inside xlsxwriter.class.php. Is there any way to accomplish that?

Thanks!
