Currently, it is possible to send an Event Registration Confirmation Email with an "Add To Calendar" button.

Unfortunately, the calendar content is only text-based, and there seems to be no way to display a personalized token {{xxx}} or any other dynamic field.

We are looking for a way to include the Event Registration QR Code directly in the calendar content. We have often noticed that event attendees have the calendar entry more readily available during check-in than a confirmation email, which often gets buried among 100 other emails.
