Export paginated reports via URL with a custom file name and timestamp suffix

Hi,

We have recently published few paginated reports to the PowerBI service and the business is loving them as it diosplayas a lot of content in printable format. We have given them the option to export the reports to PDF with url parameters.

However, when they export the reports, the report always saves with a default report name i.e. CustomerReport.pdf.

Is there a way we can add some more text to the report name, like CustNo123456_CustomerReport_20200417:13:45:00.pdf ?

Example: Currently the url https://app.powerbi.com/groups/<groupid>/rdlreports/<reportid>?rp:p_CUSTNO=123456&rdl:FORMAT=PDF generates the report file as CustomerReport.pdf. What should be the url to generate the reportname as CustNo123456_CustomerReport_20200417:13:45:00.pdf ?
