The way to link custom data to AnimationClip in Animator ?

Hi,

I have custom data that links to the animation clips in Animator.
The way I connect the data in the runtime is like this

Code (CSharp):

1.  
2. animationClipInfo = animator.GetCurrentAnimationClipState(0);
3. AnimationClip clip = animationClipInfo[0].clip;
4. MyData data = MyData.Get(clip.name);
5.  

As you can see, I am using clip.name as the connector for now, which doesn't sound like a good idea but I don't know if there is any other option.
And I just found out using the profiler that clip.name actually allocated memory as well.

So I am wondering if I am doing this wrong, or if there is any other option ?
