Restrict automatic poi creation for specific areas

Sometimes you have a specific area fully mapped out but still want to be able to travel to other places outisde the area that are not recorded.

For example i am busy making a area of the versailles Palace but i want everything inside the palace area to be created by me and not automatically when playing.

But if i want to travel for example to paris i want the POI or Area to be created automatically.

It would be handy to restrict specific areas like the Versailles palace from autogenerating of POI in those cases, whilst still keeping autogeneration on in general.
