Showing Average and other Metrics in a Pivot Table?

Hi,

Is it possible to show averages and other metrics like max/min/percentile in a pivot table?

I've attached the file I am working on with the two tabs - pivot table and raw data.

I have calculated the time it took to fill a position (column D minus column C). I want to create a summary table (I figured it would be a pivot table) that would break down by department (I was able to do that) and by whether it was filled internally or externally (I was able to do that) and by month (I was not able to do that). What i want to show in the pivot table columns though are the metrics: average, max, min. of that G column: TOF Closed to filled.
