Page transition forward and reverse [FEATURE REQUEST]

Page transitions work beautifully and really make a course look polished when used correctly. HOWEVER, here is the major issue when using a page transition.

If you add the following transitions: Push, uncover, cover, this works in the same direction for the navigation of next OR previous. 

BUT, if you press the back navigation button, the page transition moves the same direction as the next button. 

The ideal scenario would be to add an option to use a reverse transition for the previous button. This way the page transitions would look correct by moving left or right dependent on which navigation button the learner pressed.
