Can I use Cat. Codes from Customer file and use them in AAI

  Currently we have 3rd party ERP system and its setup with three different divisions. We want to keep sales, COGS etc separate for each division so we have setup each customer with three different accounts. However on JDE I would like to consolidate three accounts to one but how do I separate $$ by division using single account. We have cat codes setup for division, is there a way I can use them to map GL accounts. or do I have to use different sales order types to accomplish it, which I am trying to avoid

Thanks
