Resize an object's width or height independently.

It would be great if you could resize a platform to be wider, without necessarily having to make it taller. In fact I would love in some cases to make an asset wider, while reducing it's height. As an example, I am currently working on creating a tower and trying to use one of the circular platforms. However, in order to get the width that I need, the height is about four times what i need it to be. It would be great if I could adjust them independently when needed.
