Is there a simpler way to combine totals?

I have an order form that has multiple "single choice" questions that lead to multiple  other "single choice" questions.

I am using the Form Calculator widget and everything is working.  My concern is that if I ever need to change a prices , I am going to have to look through 17 elements to make sure that all prices are updated.

Am I missing something? is there an easier way to map the calculation values for each of these 17 elements?  A single chart would be ideal.

thank you.

If you are referring to changing the prices in calculation values:

Then I'm afraid that you have to go through all calculation values and change them manually, there is no quicker way to do that.

If you had something else in mind please let us know.

Thank you!
