Better Bounding Box Data in Geometry Nodes

If I change the size of the original shape outside of Geometry Nodes, the other cubes created in Geometry Nodes move easily, know their boundaries below.

But if I decide to change the size of the cubes created in Geometry Nodes, the shape is no longer adjacent to the original mesh. As in the image below.

Could we create a variable that will always know the outer boundaries of any object without the need to create the subtraction nodes?
