Customer/vendor statement report printout by vendor

Hi experts,

Version : 9.1 PL05

Vendor statement report(one page per vendor) layout in this version, If i am just clicking the PDF icon , SAP is creating and saving automatically all the vendor's statement as individual file in the attachment folder.

My requirement:

It is saving with the Predefined file name as "Vendor Liabilities Aging_20160412_172343" . whereas i want to add Vendor code as the part of file name.

Is it possible to achieve it ?

Thanks in advance,

Regards,
