Does a Demo Derby inventory spreadsheet exist?

I could have sworn on some video content it was mentioned that Drew had compiled a google doc or something of all the discs they'd received so far, I'm wondering where that is or if I am out of my mind. I'd hate to be sending them stuff they already have, on top of the fact that they will probably never end up getting to most of the discs anyways (seems like they have received dozens already)

I think that's just internal use only and isn't public.
