Listing Enhancements

I remember on the old version of directory press there was a place where you could add custom fields and then get them to show up in the list of package features with a little check mark if they were included and an x if they where not.

Now in the responsive directory theme I see there is a place to add custom fields to a listing but I no longer know how to make that custom field show up in the list of package features along with HTML Description, Highlighted etc.

How can this be accomplished now?
