Duplicating post-processing effect for both cameras [rift]

Hi, I am applying a series of post-processing effects to a game that uses Oculus Rift. I should apply the post-processing effects to both left and right-eye cameras. Is it possible to add the image effects scripts to only one camera and then to duplicate these effects for the other one at runtime (or otherwise)? Currently I am setting the parameters of both cameras manually... Thank you!
