Good but need help – TapGlance Interior Design Review

This is by far the easiest app I've used but I'm redoing my bathroom and I'd like to change the size of the tile (to 12x24) and the ability to only tile the bottom half of the wall. Can't figure out how to do either of those. I'd also like to maybe upload photos of my tile or flooring or.... A few tweaks and this would be the awesomest!
