How do I configure my intercompany AR address#'s to post into unique AAI's by GL Class?

JDE 9.2 with multi-currency AR and AP

I can assign AP G/L Class to "xyz" value on the Supplier master (F0401) and get the PCxyz AAI to map to a unique AP trade account. This allows me to segregate AP Trade amounts due to subsidiaries or trading partners from the general AP Trade balances.

However, when I try to do the same for AR, it ignores the G/L Class="xyz" on the Customer master by Line of Busines (F03012) and consistently maps to the AR Trade accounts (RCCAD, RCUSD) by currency.

I read the AR Implementation Guide for 9.2 and I found doc#1982411.1 Overview Setup AR AAI (P0012) which both confirm that it only looks for RCxyz after it checks for the currency AAI as RCCAD or RCUSD. I need to keep the majority of the Customer address#'s mapping into AR Trade by currency (RCCAD, RCUSD), but I wanted to segregate my intercompany Address#'s to 1 or more unique AR Trade accounts.
