Adding overlays mid scene?

So I know how to add overlays when I input my background, but I’m wondering if it’s possible to add in my overlays mid scene.
Is this possible? Or will I just have to push it out of the frame until I need it?

@overlay OVERLAYNAME create
@overlay OVERLAYNAME shifts to x y in 0 in zone #
@overlay OVERLAYNAME scales to % % in 0
@overlay OVERLAYNAME opacity 1 in 0


ahhhh thank you love xx
