I fully agree with your observation. I myself was quite surprised when I found that C1 does not have a history function à la Lightroom. For me such a history function is an essential part of a RAW converter and I miss it strongly.
I will try the Clone Variant that Doug suggested and will make a request to the Support Team as well about the missing history function. It is my experience that they are very open to suggestions and will have a serious look into it when time permits. The more users speak out the better
