Customize body text from received values

Hello,

I searched for 3 hours if there was a solution to my problem and didn’t found one so I’m asking here :

I have a contact form to signup for a course. There is a dropdown in which you can choose which course you want to go. As each course is in a different place, I would like the user who chose course 1 to receive a mail with course 1 adress, and so on..
Is there a way I can customize the email message from the value chosen by the user in the course dropdown ?

Thank you!
