ZAB Subscriptions only have the Billing and Shipping address internal id/name
I'm trying to perform a lookup against the customer to find the associated address that the ZAB Subscription has, when a custom address is entered.
I've defined a saved search with the internal id of the customer and address, but when I'm performing the lookup against the customer I don't see an address internal ID field, or even one for default billing or shipping. Technically there could be dozens of addresses involved, but I'm not seeing an option to filter by associated address internal IDs
