PO has Item its category at Master Level

• We have PO functional Catalog at 'Organization Level'
• We have defined the Item-X (M1 -Master level) and assigned to Child Org (Org1)
• Since PO item category is controlled at 'Org Level', therefore Item has 'Category_Master' as Master Org and the same item as 'Category_child' in Child Org
• when we are creating the PO for this Item-X, at PO line, the category is still showing as 'Category_Master'. Is there any way to change this to 'Category_Child'
