Official Meraki device discovery generates host objects without revealing which organization name it belongs. Out of box there is only:

{#ORGANIZATION_ID}

This reveals a use case where users could independently introduce the mapping themselves (perhaps at global level) and tell which organization ID expands to which organization name.

This requires the functinality for host prototypes to be able to expand a user macro:

{$ORG.NAME:"{#ORGANIZATION_ID}"}
