We are using zetadocs to email Vendor remittance advices and there seems to be a field where it specifies the delivery method (screenshot below). However these are all set to Hard Copy even on ones where we have the vendors email address.

What I'd like to do is export this table/field (if possible) so that I can filter vendors who have email addresses and set the delivery method on all of them to "Email" but I can't find a way of getting to this table/field.

Can anyone advise?
