I've got a spreadsheet with 25 tabs...each with it's own pivot table.

Every month I have to manually change the layout of each of the 25 individual pivot tables to add the current month, by dragging a new field into the "Column" section of the "Layout" option in the PivotTable Wizard.

Is there a faster way to update each of the pivots tables...a way that will allow changing one table to update the rest?
