Displayr has the following options for hiding objects: "Hidden from exports & publishing" and "Hidden from exports". However, there is no option for hiding from publishing only. The use case is when a document is published, but ad-hoc requests are made which need to also be added to the same document. In this case, the user will only want to keep the original pages published, while the ad-hoc pages would not be published but they should still be exportable.
