How do I change the shape of a sprite and collision box at the same time?

I’m a new Godot user and I’m having trouble with a part of a tutorial I was watching. ( https://youtu.be/xQIaRSXh4ic?t=1931 ) Apparently, the way collision boxes work has been changed since this video was made, and the handles are no longer the same as the ones that show up on sprites (it only lets you drag two handles instead of eight).

So when I have the sprite and collision grouped together as child nodes, it won’t let me change the size of both at the same time, and trying to change them individually makes it so the collision is always wider than the sprite because dragging affects both sides. How do I change the size of both sprite and collision in the same way, at the same time?
