Case Link GR-PO to LandedCost

Hi,

I have a problem, I create LandedCost Copy from GR-PO then after a while I realize there is a mistake then I have to revise LandedCost by creating new landed cost Copy From LandedCost not GR-PO :

1st LandedCost (the wrong one) can easily link to GR-PO since it is copy from GR-PO

BUT the 2nd LandedCost can't be Link to GRPO since it is copy from LandedCost.

Any solution to link GR-PO to the 2nd Landed Cost (the right one) ?

Thanks
