Is it possible to prevent swiping to a single page in a PageControl.
I.e. you can swipe to 3 of 4 pages. But the last page can only be set by the router programatically?

<PageControl ux:Name="pageController" Active="page1">
	<Page1 ux:Name="page1" router="router" /> <-- swipe to this
	<Page2 ux:Name="page2" router="router"/> <-- swipe to this
	<Page3 ux:Name="page3" router="router"/> <-- dont swipe to this
</PageControl>
