Sam,
Per Teddy and Katrin out-of-the-box you cannot sort the report. I would recommend voting for this feature in a future release or as Teddy mentions, you can add the customization. I will throw this out there as an option, run the report and click Print to Excel. Here you can sort the report and use it the way you would like.
Hope this helps.
Steve
