PDFs titles "Invoice"

Hi, I've noticed that PDFs are all titled "invoice" and the only way to change that title is to go to
/components/com_osproperty/classes/listings.php
and change manually
$pdf->SetTitle('Invoice');
Is there any way I don't know?

Hi Giuseppe,
What do you want to change?
Thanks

Hi, I'd like to change the pdf title. I think pdfs are meant to be downloaded by visitors (and printed as well, of course), and when they look at it seeing an "invoice" title I'm worried they could think they are going to be charged for whatever.
That's why a way to edit the title (or at least to take it from property title) would be great. Otherwise, I'll do it by hand at every update...
