Additional Field(s) in Bulk Registration - add company name, position, membership id, etc

I would prefer to have the function of allowing organisers to including more field when doing a bulk registration. The report generated by GoToWebinar after each event is very useful, but the attendee information is limited to name and email, which is not enough for post event analysis. 

More fields, such as company name, position, membership id, etc. would greatly help the post evaluation of each event hosted. Thanks!
