SSRS Report Subscription

I have a SSRS 2008 R2 report, with a parameter employeeID. When we do the data driven subscription I am exporting the report into a PDF file.

The PDF is saved/generated as reportname.pdf by default.Can we save the pdf asreportparameter.pdf.

Example:If we have an employeeID as 223,can the PDF generated for that emoloyeeID be saved as223.pdf.

Does SSRS support this scenario?
