Merging from a multi-select lookup field

Merging from a multi-select lookup field

I'm trying to figure out how to merge info into an email utilizing information that comes over in the multi-select lookup field. It doesn't (as far as I can tell) show up as a supported field in the email template I've created. I can merge from a single lookup field, but not multi-select. 

Please tell me there is a way around this. 

Thank you.
