I'm sure there will be a lot of ways. One way may be to use a 3-d reference. Help says:
"Refer to the same cell or range on multiple sheets by using a 3-D reference
The workbook must contain more than one worksheet. For more guidelines for using 3-D references, click .
1 Click the cell where you want to enter the function.
2 Type = (an equal sign), enter the name of the function, and then type an opening parenthesis.
3 Click the tab for the first worksheet to be referenced.
4 Hold down SHIFT and click the tab for the last worksheet to be referenced.
5 Select the cell or range of cells to be referenced.
6 Complete the formula."
Also it seems to me there should be a way to identify a range as a concatenation of multiple ranges but I don't know how to do that.
