No. Automatic v. manual calculation mode applies to the entire
workbook, not individual sheets. In fact, I believe it applies to all
workbooks open in the same Excel instance.

However, after setting Application.Calculation=xlCalculationManual,
you can use Sheets("sheet1").Calculate to cause one worksheet to
recalculate.
