Rename the file when exporting to PDF

Hi,

To perform the export, there is no option to change the name or within the editing the templates. We would need that can be included as the file name a format similar to "our company name" + "OC #00000001 ". 
Bone, which exported with the name of our company, plus the number of the purchase order.At this time makes it in this format: "PurchaseOrders_1391029680169.pdf" for example. 

In summary, it is possible to change the default name ? Is it possible? 

As we serve to display the file quickly.

Thanks!
