Occasionally, we ask guests a question which we can reasonably assume has the same answer for the entire registering party (hosts and guests alike). We'd like the ability to limit participant options to only prompt once on an event registration form.

As an example, we recently hosted a potluck and wanted our guests to tell us what dish they were bringing. For a family registering together, the user would be prompted to provide a dish for each guest including their spouse and children. This causes confusion for the registrant, causing them to think, "Do they want me to bring a separate dish for each person in my family? That's ridiculous!"
