I'm not sure if I understood your question right but yea, calc is made so you can analyze your odds against a specific hand on a specific board. There are tools that can assume a range of
hands instead of a single hand, such as pokerstove and equilab but those also require a range to be defined in order to do the calculation.
What you're looking for is, i guess an odds to improve on the flop and turn, and you can do that by learning outs and calculations on how to get the percentages from those outs, commonly known as rules of 2 and four.
If you already knew about the outs and rules of 2 and 4, please dont be offended by my answer, I might have misunderstood your question
