Set PivotTable Filter to Current Day, Current Week, Current Month, or Current Year

Hello,

I have PivotTable2 with Date Range as a Filter, Customer Name as Rows, and Sales as Values.

How do I set the PivotTable2 Date Range Filter equal to all dates in the current year? What part do I need to change in order to make it equal to the current week?

Unfortunately, I can't do that because I need all sales for a given customer to be one value, so that I can use a MAX formula on it.

I suppose that it isn't necessarily possible with a Page Filter/CurrentPage.
