Branding options in invoice

Create a possibility that you can add the invoice completely branded. Now only a logo can be added. This is really insufficient. The bill is very boring. Sending the invoice is also part of the customer experience. We want to send the best and most beautiful invoice that exists. Customers receive the automatic mail to write a review. If this includes a very nicely designed invoice, it will let the customer write a 5 star review from a 4 star. The implementation of this has a high priority and can be picked up quickly in my opinion.
