Client RLDatix would like the ability to add a hierarchy to custom fields in a similar way to how we now have hierarchical tags. This would be especially useful for custom field like Region. Example below:
Parent Custom Field = US
Level 1 = South
Level 1 = East
Level 1 = Midwest
Parent Custom Field = APAC
Level 1 = Pacific Islands
Level 1 = South Asia
Level 1 = Arabian Peninsula
