If a customer has a co0managed environment, but not all devices are supposed to receive updates from Patch My PC, the customer may want to filter the Intune Scan Wizard to only show the devices they have licenced.
e.g. 6000 endpoints total. 5000 Co-Managed, 1000 Intune managed. The Intune Scan Wizard will show data for all 6000 endpoints, which makes Auto-Publishing rules trigger on things they otherwise wouldn't have (for exmaple).
