Hey maherkhedder, thanks for the suggestion, I'm using the trick with modifying the NEW.c4d file for something else, but it's not quite what I needed.
I wish they could somehow shove the passes in render settings like with physical and standard, then the built in presets option would work.
But I did find a workaround.
Yesterday I tried making an empty scene with all my passed and then merging that one with my main work scene file. Didnt work.
However, I later realized I had the order reveresed, I needed to have the empty "passes" scene open and then merge the work file in to that one, not the other way around.
Not an elegant solution but it works.
