Create a new shape using the pen tool below the reference image.

The problem is that whenever you create a new layer using the pen tool, it is created on top of everything. When making a stroke following a reference image, the shape sometimes doesn't allow me to see the reference. It is best to always have the reference image on top with some opacity. What happens is that every time I create a new stroke, it appears on top of everything, and I have to stop, move the image position, and continue.

Can the new shape created with the pen tool be created just above a layer I select in the hierarchy? This way, I can control the order.
