Thanks, ChrisAugustin​ for your support in the AMA and for the question! Today, you can add users or devices to groups, which can then deploy apps or scripts or other policies to those users and devices. We have a lot more planned for Explorer! We'd also love to know what you want to see in Explorer, so please fill in some feedback at https://aka.ms/IntuneFeedback or by sending us in-console feedback right in the Intune admin center.
