Any way to duplicate parameters???

I am making a model that changes hair color. I want to change it twice. I have a parameter that changes white hair to red hair using a mask. I have the same hair in black. Is there a way to copy the parameter so that I can quickly change the red hair to black in a couple of clicks or do I have to redo the entire parameter? I saw options with shift + ctrl + c, but for me it only works within the same parameter. I can't copy values ​​from one parameter to others this way (I click on the hair layer, select it, copy with the hotkey on parameter 1, create a green dot on parameter 2 and paste. There is no result, it doesn't work at all).
