Pinning one image to another

I’m animating an image of a coffee cup with check boxes on it. As the animation zooms in (i.e. the scale of the image increases) I want to add ticks to the boxes. Is there any way to pin the ticks to the box areas so as the image of the coffee cup scales the ticks scale with it and stay in the right place?

grouping and scale the group?


Of course! Thank you
