"Faux Flex" and in-the-box reporting

Howdy all, 

I'm not a big box office guy, but I'm flexing that "other duties as required" line in my job description. 

Documentation shows how to build a "Faux Flex" package. Seems great, what we need, etc. 

How have you reported on identifying who are "Faux Flex" package buyers? Anything simple and in-the-box? 

Thanks in advance!
