The following problem has occurred: A client fills in a reservation form, but the time requested is already fully booked. The clerk and the client negotiate a different time, and the clerk wants to change the requested time (f.e. 18:00) to the negotiated time (f.e. 20:00) -- but as the same form has a date restriction (one cannot reserve on the same day) the clerk can't save the form at the day of the appearance.
Is there any way to give a role the permission to change every webform, without any restrictions? I.e. any changes made by role "Trusted User" will not be checked in any way.
