Add-CMDeviceCollectionIncludeMembershipRule (ConfigurationManager) - Configuration Manager

Use this cmdlet to add an include membership rule to a device collection. An include membership rule includes the members of another collection to the device collection where the rule is applied. You can't add membership rules to default collections. Any collection that you target should have an ID that starts with the site code, not SMS. You can include a default collection, so the ID of an included collection can start with SMS. Configuration Manager dynamically updates the membership of the device collection on a schedule if the membership of the included collection changes. When you add an include membership rule to a collection, resources may become members of the collection. This action can cause any software or configuration deployment to apply to devices in the included collection. For more information, see How to create collections in Configuration Manager. Note Run Configuration Manager cmdlets from the Configuration Manager site drive, for example PS XYZ:\>. For more information, see getting started.
