Can't derive natural account in SLA for AR Retainage.

Summary:

When processing project billing invoices we receive a billing event for Retainage and one for Gross Invoice. We are unable to derive the retainage AR account segment separately from the regular receivables account. What SLA source can we use to derive a Retainage Account separate from the regular receivables account? Event type is not available as a source.

We want to Debit Retainage to effectively reduce/credit the Gross AR by the retainage amount.

Thank you!
