Resetting Curves in Duotones

I created a duotone and played with the curve settings. However, now when I change the mode to duotone in any other pic, the curves are the same. I'd like to get the curves back to the default settings so I can start over with each picture and having a hard time doing it manually. Is there something I'm missing? Can someone give me a hand?

Thanks a lot-
Rick

Save the duotone curves and then just load them for each picture.

Thanks for responding, Bob.

I've done that and it works fine for some images. But for others, I want to go back to the default curves and then adjust them as each picture calls for.

Everytime I open any image and change the mode to duotone, PS automatically opens with the settings that I used previously instead of allowing me to start over again from the default.
