For many conferences, exhibitors need to have complete contact information for each registrant. This is usually included in the badge code to be scanned by the exhibitor. Currently, to use the existing export options would require complete contact information be entered for every single registrant. Just having the biller info able to autocomplete though useful, does not help in this case. It would be nice to have a config file that can point to a data table for auto population based on the entry of a field. No login would be required. If the registrant puts in the correct value for field "E", fields "F", "G", "H", etc., auto populate based on the results of field E.
Example, if the registrant types in a company member account number or id, then the appropriate address information is auto populated. This is important when you are performing group registrations from companies that may have 20 or more individuals coming. Currently, this can somewhat be faked for individual registrations using Community Builder where you can make an account number or member number/id the username for authentication.
