Easy way to update formulas when adding new spreadsheets?

This is what My spreadsheet looks like:

As you can see, the "data results" tab tallies data from the Chart 1, Chart 2, etc. tabs. Untitled.png

What if I want to add new spreadsheets to my workbook? Chart 9, 10, 11, 12, etc. All identical. Is there anyway to update formulas in "data results" other than doing it manually?
