Is it at all possible to disable the attached invoice pdf? i only want to send the customer an email that says thank you for the order, and then generate an invoice on my own. At the moment i am not having any luck with this so i have resorted to emptying the invoice layout, but this looks a little unprofessional if you send the client a pdf with nothing in it.

joomla 2.5.9
virtuemart 2.0.20b
artio vm invoice 2.0.24

Thanks
