Help: COPA with actual cost

xiaoerp

1) After billing, a line item with billing qty, actual sales, standard cost estimate is written into COPA report. (2) After actual costing run(CKMLCP) and periodic valuation in COPA(KE27), a new line item which refers to the orginal COPA line item is generated  with cost difference (Actual product cost - Std cost estimate). But the new revaluated line item has no information such as billing qty,
My question is
Can actual cost updated by periodic valuation be generated in the same line as the one generated at billing . That is, for one billing document, standard  cost and actual product cost are in the same line.
