List of select choice on a multiple select field

Hello,

I’m trying to add a multiple select field using pipe system to provide to my users a list of files to receive by email.

For that i have this shortcode :
[select* methodology multiple “File A|url_file_a” “File A|url_file_b” “File A|url_file_c”]

And i want to have on email template a results like this if user select only File A and B :
Your files :
File A : url_file_a
File B : url_file_b

But for the moment the user received something like this :
url_file_a, url_file_b

Can you help me.
Do you have a solution ?

Thanks.
