Custom invoice email templates

I'd like to see the ability to have greater control over the invoice email template that gets sent to customers. Currently there are two links to view the invoice online, which may cause issues for those using third party payment platforms. This includes the green "View invoice" button in the top right corner of the current invoice email template.

We would love it if we could remove these "view online" buttons or have greater control over the email invoice template. This will vastly improve the user experience for our customers who could be confused when viewing the online MYOB invoice link, when they are used to paying the invoice on a different website domain (such as paypal).
