Printing filename

(osx) when printing an invoice, and selecting “Save as pdf”, the filename is always the sam.
I think this is because the title-tags is fixed. It would be nice to have the title tag set to:
"{company name} invoice {invoice number}"

I think this will cause the print dialog to set the filename.

If you are using Print button, Mac OS X will probably use name of the screen as filename.

I’m planning to make some changes so PDF could be generated directly within Manager, then it will be possible to control filename too.
