I have about 25 datastores that I am exporting to 25 worksheets in a workbook in Excel with the below command:

$report->run()->exportToExcel()->toBrowser($this->session->userdata('campaign')."_workbook.xlsx");

I'd like to add a few rows at the top of each worksheet with info about the username, date of execution, company, etc. Is this possible to easily do?

Sorry, I meant putting not purring! BTW, I found the exporting with a template.
