Snapping images in “Combine photos” PS express mobile

Not sure you actually read his question. Nothing that I could find in your response indicates how to snap to grid a photo in the combine photos function.  I take an image, duplicate it then want to be able to move both of them to opposite sides of the frame and have them line up. The only way I can see how to do this is to zoom in and try to get them to line up by hand. This is an awful way to do it. It was very simple in PS mix.  Please answer the question rather than posting a link to a genetic 'how to use the app'. Is it possible to do what the person above and I have requested? Yes or no?  And if not, why not? We seems like are now paying for an inferior app.
