Webform integration: Allow specifying default Fill PDF template

Having implemented Fill PDF on a couple sites using Webform, the standard use case is to send a link to someone in an email after the form is submitted. As part of making the link the form more portable, having a default Fill PDF template associated with the webform itself would be nice. This would be done via a textbox on the Webform settings page (per Webform).

At this point, this is an idea, but I'd like to hear if people actually want this or not.
