I want to display a banner in a zone only if it there is no banner of the same campaign in another zone which is rotating multiple campaigns.
In other words: If its not the turn of a banner in zone A, then show an other banner of this campaign in zone B. If the banner is shown in zone A, then zone B should be empty.
I have enabled "Don't show a banner from the same campaign again on the same page", but how can I set the order of which banner used?
Many thanks for help!
