I am building a block that allows admins to add a 'Call to Action' button and of course it needs to point to a specific landing page. One of the pages I need it to point to is a 'Registration' page BUT this page is a 'system page' and the Page Selector helper does not offer the choice of showing system pages even though I'm logged in as the Super User. Is there any EASY way around this so my naive users don't have to jump through hoops just to add a button to a system page?
