The only method I’ve found so far is by editing a core file, which isn’t “ideal”, but can be done.
Note: Make a backup of the file before editing.
Open /DT9/framework/new_class/ppt_2_layout.php then look for
$access = _ppt('listingaccess'); (around line #627) and replace it with
$access = ('post' === $post->post_type)?0:_ppt('listingaccess');.
Save the file and check.
