Nth Largest Value In Pivot Table

I have a spreadsheet with items and their maintenance dates. Each item may be listed multiple times with various dates. I want to create a pivot table that will show the most recent and previous maintenance date. The most recent is easy by using the built in "max of" in the Pivot table Wizard.

how to use the "Large" function in a pivot table? or is there a better way to get the 2nd largest value? Auto Merged Post;Bummer! No answers yet. I thought there might be some experts out there that would have a really tricky way of doing this.

" In formulas you create for calculated fields and calculated items, you can use operators and expressions as you do in other worksheet formulas. You can use constants and refer to data from the report, but you cannot use cell references or defined names. You cannot use worksheet functions that require cell references or defined names as arguments, and you cannot use array functions." I think I may end up adding a column to the original spreadsheet to create the 2nd largest value and use it in the pivot table.
