I don't think I was clear. I was looking for an object that can be resized in both the way a tilebackground is, and a sprite is. Not one command that does both, but I want to have both options available. If this is still unclear an easy way to understand what I mean is to take an image, and make a tiledbackground with it, and then also make a sprite with it. Resize each one in the editor and see what happens. The only difference is that I don't necessarily need it to tile repeatedly.
It looks like I can do this with Rojo's spritesheet plugin by modifying the width and height vs the subwidth and subheight.
