How to change PO Purchasing Line Type which is defaulted from PR without disturbing the Line details

Summary: Hello Oracle Experts! When converting the PR to PO, the Buyers need to update the Line Type for few lines because there are chances that the users are choosing it wrongly in some cases, but when changing the Line Type, the entire Line gets refreshed and all the Item details are getting removed and they are forced to re enter again for that particular line by referring the original PR.

The business users are mentioning in the Oracle EBS they will be allowed to update the Line type without making any disturbance to the line details. So is there any workaround way to achieve this. Pls. confirm.
