Feature Request: Material Functions supports Post Process Nodes

Hi Epic Games,

i am working with PP Mats currently. It would be cool if there would be an option to make a material function working with Post Processing Nodes. Maybe a new option. I would like to put in Nodes like SceneTexture:PostProcessInput0.

Sorry, my Paint made this extra graphic (bottom left) a little bit blurry.

Cheers,
