How to center prefabs' children to (0, 0, 0) without changing their position relative to each other

I want to center prefabs’ children to (0, 0, 0), I tried to select every child and set their position to (0, 0, 0). But the shape is different from the initial shape.

How do I center it without changing the shape?

Create a new GameObject and call it “Cube Handle”.

Take your six sides and make them children of the new GameObject.

Now instead of selecting all six elements to move your Cube, you only select and move “Cube Handle”.
