shared material with multiple texture offset speeds

Hello,

Is there a way to have a single Shared Material that can have multiple texture offset speeds without effecting the speed of all the instances that use this shareMaterial? I have different instances of a game Object using this shared material but would like a different offset speed for certain ones.

I am asking because using texture offset breaks batching unless set up as a sharedMaterial and I have several instances using this shared material. When I alter the texture offset speed all the instances are changed.

Any ideas would be much apreciated.

Below is my code for one sharedMaterial:

 using UnityEngine;
 using System.Collections;
 
 public class ExampleClass : MonoBehaviour {
     public float scrollSpeed = 0.5F;
     public Renderer rend;
     void Start() {
         rend = GetComponent<Renderer>();
     }
     void Update() {
         float offset = Time.time * scrollSpeed;
         rend.sharedMaterial.SetTextureOffset("_MainTex", new Vector2(offset, 0));
     }
 }
