Mac OS Patches

New Contributor II

I'm looking at patching and reporting.
I would like to create a smart group based on when a patch is installed relative to when it was released from Apple.
A smart group of computers that haven't installed the latest patch released by Apple in x-days kind of a thing. Is there a way to accomplish it?
Apple publish their release dates at but I would like to avoid a lot of manual work of creating a smart group criteria for every singel update released by Apple.
