How to use AutoTiling for BoxCollider2D in child gameObject?

Question

So basically I have a gameObject "PlatformA" with a SpriteRenderer attached to it. The Sprite that is used is 9-sliced, so that when you scale it, the borders remain the same size (All of that works fine).
Now I have another gameObject "PlatformAChild" that is a child of the gameObject "PlatformA". This gameObject possesses a BoxCollider2D, which I want to scale according to the changes of the SpriteRenderer in the parent gameObject.
How can I do that? ticking the "Auto Tiling" box doesn't do anything because there is no SpriteRenderer attached to the child, only to the parent.

I fixed the problem myself by creating a workaround:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 [ExecuteInEditMode] //makes the script operate in Editormode
 public class ScuffedScript : MonoBehaviour 
 {
     
     private SpriteRenderer parentSpriteRenderer;
     private BoxCollider2D scuffedCollider;
     private void Awake()
     {
         parentSpriteRenderer = transform.parent.GetComponent<SpriteRenderer>();
         scuffedCollider = GetComponent<BoxCollider2D>();
     }
 
     
     void Update()
     {
         scuffedCollider.size = new Vector2(parentSpriteRenderer.size.x, parentSpriteRenderer.size.y+0.1f);
     } 
 }

You simply need to apply the code to the child(the gameObject with the BoxCollider2D that you want to change).
