Debit Memo's Processed from Order Management

Hi,

There is a requirement to enter debit memo's for previously booked and Invoiced sales orders. Is there a way these debit memo's can be processed from Order Management than having to create them manually in receivables and reference this sales order ? If we create a new line in the existing sales order, it will create a new Invoice, instead can we associate the new line to create a debit memo ?

Thanks
