Allow merchant branding in email footer

Hi

The footer in emails sent to buyers currently looks like this:

[Moonbase logo]
This email was sent to [buyer email address] on behalf of [merchant name] by Moonbase.sh — an authorized partner powering software delivery and licensing.
[Moonbase address]

Would it be possible to customize this footer?
For better brand consistency, it would be great to have an option to display the merchant's logo and address instead.
Perhaps the Moonbase footer could remain the default, with the merchant-branded version becoming available once emails have been configured to send from the merchant's own domain?
