Adding labels to an image target?

Hello folks,

I was wondering if there is a way to add some kind of labels to an image target. Say, your image target is car, you may want to add labels showing thing like "this is the engine", "this is the wheel", "this is the door", and so on.

Does Vuforia already have this sort of things? If not, what approach would you suggest to achieve this?

Thanks in advance.
