We have sponsorship levels for our 5K race that include registration for UP TO 10 individuals. Oftentimes sponsors only send a few people - but on the online form, the only options are to enter information for a full 10 registrants or select "this registrant will provide information later at the event" for 5+ "registrants." This then creates 5+ "shell" registrants that never actually existed.

We need an "I am finished adding registrants" option to skip ahead to the next section after they registered their team of 4 or 8 or whatever people.
