Add option to scan which updates are enabled for applications that *aren't* present in your environment

In the Patch My PC Publishing service, under Updates, in the "Scan Configuration Manager Database for Supported Products", it would be helpful to have an option to scan which updates are enabled in the publishing service that are NOT detected in the inventory data being queried. This would allow administrators to identify if there are updates enabled for an application that is not present in their environment. Administrators could then use that information to disable those updates in future syncs and preserve resources.
