Can my spreadsheet pricing calculator reference values from another file?

PRESSERO > *Pressero FAQs
Question:
I am thinking we could have a central Excel file we upload and have all the calculators reference values in that file. So I could have my paper and other material costs entered once and then referenced by all calculators. Will this work? 
 
Answer: 
Unfortunately, no. Values from another excel file cannot be referenced in a pricing calculator pricing method.
