Formatting how fields display in email template

I have a field being displayed in an email template (in the email body) … it’s a multi-choice field, and it displays the selected choices like this:

Deicing Truck, Tank, Support Vehicle

is there a formatting function I can use (at the email level) to display the values like this:

Deicing Truck
Support Vehicle

… or can someone point me in the right direction to look it up (haven’t found it on the wiki yet)

Thanks in advance…
