Intercompany Payable and Receivable representation in FRS reports

Hi,

Currently we are maintaining only one natural account for Intercompany Receivable and Payable. In other terms, if the account has a positive balance, it will be considered as a receivable and if has a negative balance, it will be considered as a payable. We have the requirement of mapping the above in FRS where if the account has a positive balance it should be displayed under Current Assets and if its negative balance it should be displayed under current liabilities.

We can map the said account in both section. However, need a way to segregate the balance classification of it based on the above mentioned criteria.
