Before or after having planned editorial pages, you can also plan advertising formats. An advertising format is a Placeholder on which you can place an advertising booking.
From the Advertising Format Tool, you can select the advertising format you prefer and Drag&Drop it on a page, to book the place.
 

Moreover, you can assign a NOTE to the Advertising Format Placeholder, by right-clicking it with the mouse and choosing “Modify notes”. This function may be used when no bookings have arrived yet in the system, but you want to start reserving this space for a special need.
