Windows Missing Patches Report Help

Hello all,

I am new to PDQ and I am already a huge fan. The ability to generate reports is very useful but I cannot for whatever reason seem to generate a report for missing Windows patches. Specifically I am trying to generate a report that shows the server and then how many Windows Updates it is missing, preferably with a number. Firstly, is this even possible? I understand that it might not be possible in PDQ which is fine! I am wondering if I am able to pull the information and then parse it in excel to achieve what I want.

Secondly I have tried a couple of different combination but really all I can definitively get is patches that were installed within a time-frame. Which isn't bad but its not what I am looking for. This other reports I created shows the server and then each program that is in "Old" collection, but I also don't think that is completely accurate. For that report definition see the attached photo. It is pulling from the "Servers" collection.

Any thoughts? Anything I should try? Any help would be greatly appreciated.
