If you're consistently pulling data from the same place on each sheet, you
could use indirect and address. For example, if you want to pull data from
Sheet2 cell E1, you could put 'Sheet2' in cell A2, then the formula
=INDIRECT(ADDRESS(1,5,,,A2)) in cell B2. Fill column A with additional sheet
names and autofill column B with the formula. So you'd have to enter each
sheet name once, but then you could reference it in multiple such INDIRECT
formulas.
