You can always edit and come up with a custom list, and change what is 
shown in the drop down menu (i guess) - but the off-the-shelf list does 
invisible to all only.

It is common for users to toggle between invisible to all vs other 
privacy lists - custom lists are usually pretty rare. And they can use 
custom list editor.

That being said, it is easy for clients to manage order such that 
different regions deal with different aspects (so not much change in 
order value is required between edits).
