SSS Pass

Currently you can only get SSS Pass by rendering the scene 2 times. And for each shader that has SSS, you also need to create a duplicate without SSS and in the duplicate scene change all shaders to shaders without SSS. In order to replace shaders, suppose you can write a Phyton script. But increasing the render time by 2 times in some situations is too resource-intensive when SSS already requires a large number of samples.
