How Do I Select Multiple Sheets In Mac Numbers (is It Possible?)

Mac Numbers question: is it possible to select multiple worksheets, and make calculations in 3 dimensions? For example: a sheet for every month of 1 year, with detailed daily incomes and expenses. At the end of the year I want to make (with formula vertical lookup) one table with the total amount of each type of income and expense.
This is easy in MS Excel, until now I didn’t find a way to do the same in Mac Numbers.
