@MadelineStefanou - This was a MOTM topic in 2014. @DougJenkins and I met at the 2013 DC summit. I did a webinar for him and his staff about a month later and they took off with the concept so well that he did the v2014 SOTM session on PTQ's and Excel Pivot tables.
Back in 2013, we had a 90M webinar where I presented PTQ's, Pivot tables and other topics. It was recorded and is available for playback at the link below. Warning - There were a number of technical difficulties encountered. Audio doesn't start until 13:55 into the session. The actual PTQ discussion doesn't start in earnest until 31:06 Pivot table discussion starts at 1:06.00

If you have some time, it is a good highlight of the potential.
