I'm not sure I understand your question. You can certainly refer to data.Url inside the item renderer. If you mean using a filterFunction with data.Url, you would have to apply it inside you're item renderer and most likely make a copy of your original ArrayCollection in each itemRenderer to apply the filterFunction to so that each renderer is filtered without affecting the others.
