Hello there - is there a specific type of sort you are trying to perform? If not just by using the default Filter Icon in Excel/ Google Sheets will be fine:

Hitting the sort button will allow you to manipulate the order which you see the PA displayed. In excel if you need to run a double sort simply hit Data -> Sort and enter the details in the dialog.
