TOPIC: Field not visible in registration form, visible in attendees

I need special field witch is not visible in registration form but visible in frontend Attendees list.
I need possibility from administrator panel to check some attendees who will be selected by me to work as range officers on my match and that all attendees can see who of them are range officers.

You can designate any field as a "hidden" field so it doesn't show up in the registration form, but the admin is able to use the field when editing the record. However, hidden fields can not currently be shown in the frontend attendee's list. Hidden fields CAN be included in emails with the email tags.
