How do I disable automatic sprite frustrum culling?

I noticed that some of the shadow light's shadows disappears in certain areas, and I soon realized that the culprit was the sprites with the shadow caster behavior being automatically culled/not rendered when outside the screen. I understand that this is for optimization, but how would I turn this off for individual sprites? I wish to have the shadows be visible (rendered from the affected sprite) even if the shadow casting sprite isn't currently on-screen. Thank you.

I 2nd this question! I'm trying to make a realistic shadow-casting sun in a 2d platformer, but when objects get too far away the shadows pop in and out!
