Custom Site Billing Emails

We'd like to request custom billing emails for Site Subscriptions (Subscription invoices, missed payment etc).
The emails we then receive would generated by Siteglide. This would mean you can automatically include more information and data about a site (name, current url and more).
For now, we can search by invoice ID in portal to find out more, but it would be a nice bonus to be able to see this information directly in the automated emails.
