Ability to toggle between laying a block as a floor piece or a wall piece

If you are digging out the ground and replacing the terrain, it can be extremely frustrating to get in a rythmn of laying floor pieces, and the accidentally stack a few as a wall because you moved an 1/8th of an inch. Its even worse when the terrain you're working with is tough for your level. I think it would be a huge quality of life improvement if holding terrain peices offered a toggle option. This would be a great accessibility upgrade that simplifies a task that should be fairly easy for any player to begin with. The same input that cylcles through hoe/shovel area sizes would be perfect.
