I have been asked by a client whether there is an option to send separate booking emails for manual payments. The client invoices customers for paid events.

When a booking is made, the initial confirmation email is sent, along with an invoice. When the customer's payment is received, the record is marked so and a second identical email is sent along with an identical invoice. This is causing confusion with many customers.

Is it currently possible to setup different emails for this? If not, can it be added?
