Adding signatures to invoices

Hello,

With the change in export regulations and the requirement to now include a signed invoice with shipments is there a way RC can add a signature from a .jpg or .png file automatically ?
eg, DHL require a digital signed invoice to be uploaded on to their booking system.
An option to not have signatures on domestic orders would be useful too.
It's taking a lot of time manually adding a signature to a pdf.


Thanks,
Dave.

That should work but I'm getting an error when previewing the Invoice templates :-

"We are sorry, but an error has occurred. Please click on the back button and try again.
If the problem persists, please contact the merchant."

So it's difficult to edit the template and see how it looks. How do I preview the edited template


Thanks,
Dave.

Hello Jake,
I've added an invoice template as suggested and working well for us.
The preview button in the RC document template page still isn't working though.
Thanks for the help.
Dave.
