Connecting two blendshapes

I have two SkinnedMeshRenderer objects (a character and eyelashes) that have matching blendshapes for different facial expressions. Is there a way to set the values for each blendshape on the eyelash object to match whatever value has been set for the identically-named blendshape on the character object?

Solution - I cobbled this together using my limited coding knowledge… this script is attached to the eyelash GameObject and drives its blendshapes with the values of the matching blendshapes on the body GameObject. The order of both objects’ blendshapes needs to match so the blendshapes have the same index numbers. Maybe there’s a better way but this seems to work just fine for my needs.

using UnityEngine;
using System.Collections;

public class EyelashBlendshapes : MonoBehaviour

    int blendShapeCount;
    float weight;
    SkinnedMeshRenderer skinnedMeshRenderer;
    Mesh skinnedMesh;
    GameObject source;
    SkinnedMeshRenderer sourceMeshRenderer;

    void Awake()
        skinnedMeshRenderer = GetComponent<SkinnedMeshRenderer>();
        source = GameObject.Find("Genesis8Female.Shape");
        sourceMeshRenderer = source.GetComponent<SkinnedMeshRenderer>();
        skinnedMesh = GetComponent<SkinnedMeshRenderer>().sharedMesh;

    void Start()

        blendShapeCount = skinnedMesh.blendShapeCount;

    void Update()
        for (int i = 0; i < blendShapeCount; ++i)
            weight = sourceMeshRenderer.GetBlendShapeWeight(i);
            skinnedMeshRenderer.SetBlendShapeWeight(i, weight);
