The customer would like to make Access screen show up the end user's system name instead of the device name. It means "Delivery system" instead of hostname/IP Address as the device name.
Some of user may know the hostname but most users understand the system name like the "Delivery system" instead of the hostname. Hence, the end user expects to show up the system name on the Access screen to understand easily for the users.

Just set the name you want like the "Delivery name" in the Name field on the device(Devices >> Managed Devices).
After answering this, the customer understood it but the end user has a few systems like the "Delivery system" and "Account system" on the same box. Then, she needs to set 2 devices with the different names and 1 IP address. The expectation cannot be met by PAM's design behavior.
