I have a feeling I know the answer to this, however, I'll give it a shot - please reference screenshot - is it possible to add a Decision box field to a calendar form that would set the event to "all-day", so the event then shows in the all-day section of the calendar report/weekly view?

If this is not possible, when will this be possible? I see an existing request from 8 years ago. This is a feature many users need.
