There’s no option to populate the body based on other fields. I can think of three workarounds:
1) If you leave the ‘body’ field blank the plugin will default the title & body based on the full address.
2) You could specify a body custom field and then type in the full address in that field (which requires some redundant data entry)
3) You could also write some custom PHP code to populate the body field based on the contents of the other fields.
I hope that helps!
