Could you please add the option to change the system default for "invoice delivery" to "to be emailed". Currently it automatically opts for "to be printed" but most clients like to receive invoices via email. I know I can choose this option in each customer card but it would be much easier if it automatically chose "to be emailed" as it's another step I have to do when creating a new client card and it's a lot of time when adding many new clients every week.
