I think you're going to have to look at this :

There is this..
CurrentPage As Int
Get or set the current page. Page numbering starts at 0 like an array.
So it is possible, but suspect that it may well try to stop you doing that, as it consumes all gestures, but not sure if you've placed the button outside of the View, so in another View, then you may well be able to do what you want..
