How to create downloaded file name dynamically in SSRS reports

Dear All,

i have Implemented the SSRS report using Fetch XML for the contact Entity.

Now i want to achieve this:

Suppose One of the Contact Record i have opened Whose ContactName is Contact-001 and when i click on the Run Report from the particular record form ( Contact-001) that SSRS report will run, Now when i export that report to the PDF format the PDF name will come as RDL Name instead of that i want to print Contact-001 as that PDF Name.

Please Suggest me on the same.

Regards,

Krishna.
