Link Manual OR to OB Line

Hello

Need to create Manual Order release with line item and then to link it to a created order base line

The Case that I have a certain Packaged Item in OB line "Scrap" but once I made order release instruction it will release with Scrap Item

But Business need that the order release has a different Packaged Item "Hard Scrap" or "Soft Scrap".

User Won't be allowed to change it manually so we need to create OR first with the desired Item "Hard Scrap" and then be linked to OB Line "Scrap"
