Hi Julio,
Happy 2023! I raised this issue a while back and my understanding is that the Chaos team are working to bring the "GOBO" feature to Corona Renderer too. Not sure when this will actually happen, but I am sure they are working on it as everyone needs this! At Oxocan, we use Arnold Renderer when we need the GOBO utility for area light or spot light as Arnold offer IPR preview as you are working on your scene. We aim to use Corona on some scenes, but when we require more delicate renders we stick with Arnold!
I hope this helps for now.
Warm regards,
Ian
