Mirror / flip Curve?

Using a Curve in a Timeline and need it mirrored/flipped for another. I don’t want to use “reverse” just separate but the exact same curve. Is there any way to do this either in the curve editor or inside the timeline?

Is there a reason why reverse is not an option for you? It seems to me that situatuions like these are one of its main uses

Needs different variables at finish.
