Defining tap-able areas in lovelace

I have multiple picture elements in a single card that blend together so there aren’t any visible overlaps for lighting and so that creating the images is uniform and fast.

The problem with this is that there’s no way to distinguish between the tap-action areas for each image (i.e. each light) without adding icons or other buttons to address the light.

What I’d like to be able to do is tap a room and have that light respond, or tap and hold and set the brightness.

At this point, in the list of elements under the picture-elements card, the most recent, or the last element defined is the one that is seen as the tap-action control.

Is there a way to define tap action areas on a lovelace screen that are invisible and can be positioned with accuracy?
