I love this feature of LISE, because it allows me to let the user target
specific pages for a certain item. However, I use it for restaurant menu items
and I have just a couple of pages I want the user to be able to target. Nothing
bad happens when a user selects a page that doesn't support the LISE instance,
but still it would be nice if I can narrow the displayed pages a bit to keep it
nice and tidy. By providing a range or maybe a parent page (where only children
of that parent are shown as options).
