Quickly Customize an Excel Toolbar

In one of the Excel newsgroups last week, someone asked how they could update several pivot tables at the same time. They were tired of selecting each pivot table separately, and clicking the Refresh button.
In an Excel workbook you can refresh all the pivot tables and queries if you click the Refresh All button. That button is on the External Data button, which appears automatically if you click in a cell that's part of an external data range.
However, if you don't have any external ranges in your workbook, you can add the Refresh All button to the PivotTable toolbar, so it's easy to find and click.
The quickest way to add this button is to click the Toolbar Options button at the end of the PivotTable toolbar. If the toolbar is floating, you'll see a large triangle to the left of the Close button.
If the toolbar is docked, there's a small triangle in the bar at the end of the toolbar.
Click the Add or Remove Buttons command, then click PivotTable
You'll see a list of all the standard commands that can be added to the PivotTable toolbar.
Click on Refresh All, to add it to the toolbar.
Now, when you want to update all the pivot tables, just click the Refresh All button.
