We have added a new kind of field to the form designer: The Multi Lookup field. A Multi Lookup field is like a List Selection field, except it allows you to look up more than one value in a single selection action. For example, you might have a help desk application, and when select the service rep’s first name you could also have the rep’s last name and phone number pulled into the record at the same time.
