TL;DR - Either provide an admin only question that is viewable by a registrant in their entry, OR provide ability to have a question that is not editable by a user during their session.
It's fairly common for tournaments to have an approval process before allowing a team to participate in their event. For liability reasons, tournament/event based organizations often require that, after a team has registered, each individual on their roster must go through a separate registration session to sign a waiver and/or provide additional info (proof of eligibility, birth certificate, etc).
As of now, there isn't a good way for teams to track which individuals have gone through the separate registration session. This causes teams to be stuck in limbo, and leads to a ton of emails to administrators asking which individuals the team still needs to chase down.
By having a field within registration that isn't editable by a user, or an admin only field that can appear in their entry, teams can easily track their approval status by viewing their registration entry, and see which athletes have/haven't signed the waiver.
This a growing need by our event based clients, and is a feature offered by multiple competitors.
