Links to bring up a menu

I have a small site with a number of pages that should be only visible to either US / UK / Rests of world / or Europe.

I think your advanced plugin would work. But the icing on the cake would be to allow the user to switch country if they happen to be on the wrong version due to VPN or they deliberately want to see the content for another country. Is there any way to generate URLs for specific menus? Thanks,
