I’m not sure I understand what you’re asking for. The list of authorized devices shows only the devices linked to your own account. IIRC this includes devices of managed users which are technically linked to your account.
There’s already an existing feature suggestion discussing an option to rename devices on the authorized devices list. I suggest you comment/vote in that thread in order to avoid distracting/dispersing votes (I’ve therefore updated your OP to avoid further confusion).
