I've double check that this feature is still on the wishlist. Features on the customer wish list get development prioritization based on a combination of customer demand and difficulty to implement. Since this is a feature which is rarely requested and would require a significant amount of development, I can't unfortunately not give an estimated release date.
The best workaround currently is to find a third party tool which has some sort of location tracking function and deploy it on all your assets using the deployment module.
