We are sending 2 different certificates to our students. One is Participation and the other is Achievement. Normally, we should send 2 times email for sending both certificates. My suggestion is to send just one email instead of sending 2 times. If we can put the Wallet attribute to the sending emails we will just generate all certificates for a single participant and send just one email which contains the Wallet link. Thanks to the Wallet functionality they will see every single certificate which generated but wasn't sent individually. How does it sound:) I hope it will make sense from your perspective too. Many thanks for considering my request.
