What is the internal field ID of the subcustomers list? I can't seem to locate the internal field ID of the subcustomers list on parent customer records. It's not on the customer record page on the Record Browser, and it's definitely not a custom record or list, so I'm kinda lost. Any help?
For context: I'm writing a script to update the billing address of all child records when the billing address of the parent record has been changed. So I need the field ID of the subcustomers list so I can loop through each record.
