Agreed; that's why I set aside invisible tiles of all kinds (About 1 row of tileset) I won't use all of them and some will be spare. I also keep the sprite tiles free until then when I can dump eye candy into them. Since TOM makes this difficult I am testing a different level editor which may have a better feature fr this.
