OWC Pivot Table

Hi,

I created an Office PivotTable list by first creating an Excel pivot
table and then saved it as a web page.

When I click on the html file, it opens in the browser, with the pivot
table in it.

It is possible to select one item in the drop-down menu's, and the
user, as an option, can allow for selecting multiple items.
This option is OFF by default.

My question is: is there a way to change the pivot table ( html object
), so that this option is ON by default ?

Thanks,

RS.
