I found the aggregated report in this video very interesting. I've been using GTO+ (its cheaper than PIO) to support me doing some of the homeworks up till now. This sort of sweep is probably the next step up in terms of work I could do.
Can anyone point me at a good article or something on what an aggregate report is and how to build one? I found the below link, which I will watch at some point, but no idea who the guy is or if he is giving out good information.
Thanks for your help
