CoursePress Pro Email Mergetags / Shortcodes

Hello,

I was hoping someone could help me with the possibility of creating custom mergetags or custom shortcodes to place within email notifications.

I found this post: https://premium.wpmudev.org/forums/topic/confirmation-email-short-codes, but it appears to be for Appointments+ and not CoursePress Pro.

Basically I need the ability to add:
STUDENT_LAST_NAME as well not just first name. And I also created a few custom fields during the registration process, so I would like to pull in some of those custom fields as well.

I have this post actively going: https://premium.wpmudev.org/forums/topic/student-registration-page-customizing#post-808813 which has my custom fields I have created (address, phone etc.)

Any further clarifications on this would be awesome!
