Another Appointments+/marketpress coding question

Hello,
I have used the following code in the post and it works very well: https://premium.wpmudev.org/forums/topic/marketpress-and-appointments-product-info-email#post-375011

It appends information from the appointment into the admin email I receive from marketpress. My question is: Can someone help me modify this to also show the stuff from the "additional fields" add on for appointment plus? When you create these fields it makes email macros, In my case I have two necessary text fields with the email macros being "Option1" and "Option2"

Can someone help me modify that code to also pass through these additional fields like the other fields already being passed?

Thank you very much
