Future Date merge fields for appointments

I am Have appointment sequence for my clients, but when i place appointment date field , it only shows date format like " I am looking forward to meet with you in person 11/20/2018 "

I am looking to get something like this merge field
[~today.date|full~ >>Result>> Tuesday, March 15, 2016]

I mean future date in this format .
