Late Availability listing - shortcoming

When a site has no vacancies it is removed from the list.

Now that may appear logical but unless you are certain which region a particular site is listed in, you can't be sure there are no vacancies because you may not be looking in the right place.

For example Henley Four Oaks is listed under Cotswolds. There may be others where it is not immediately obvious which region they are in.

Why not leave it as a full site listing but show "zero" when a site is full.
