Hi @genedupre,
Thanks for the feedback and interest in contributing to the Mender open source project!
This is supported, and perhaps more conceptually aligned, with identity attributes (not inventory).
Identity attributes are intended to be unique (as a set about a device), unlike inventory which is more informational/general purpose. You can read more about identity attributes here: https://docs.mender.io/2.3/client-configuration/identity
In your screenshot you are using mac as the identity attribute to show, but if you added hostname to identity you could select that as well from the “gear” icon in the header row.
Does that make sense?
