How to actually use Light2D without relying on sorting layers

I’m making a 2d isometric game, and I’ve gotten to the point of lighting. Now here is the issue, if I want for example an object to light up behind the player, the lights can only target an entire sorting layer, and I can’t simply move the object I want to light up under the player because the object needs to be on the same sorting layer as the player to sort properly with yz sorting cause isometric game. Is there any way to make the light sort just like any other object or can it only light entire sorting layers?? How is it intended to function properly in this instance?
