OM Workflow Customization

We have a requirement, i.e. the billing invoice (AR invoice) should not be created for the orders which has a process flow assigned as ‘Line Flow – Standard Service’.

As per the standard workflow process after fulfillment the next step is Invoice to Interface Lines.

Enter Line -> Fulfill Deferred -> Fulfill -> Invoice Interface Lines -> Close Line

Is there any way to restrict or skip the Invoice Interface Lines step without customizing the workflow process?
