How can we have the Line Item information carried over, after modifying Committed Line Items?

In a change order, when we select "Modify Committed line item" in the Standard Tab, the only information that gets carried over is "Short Description," which causes users to mistake.

In the details tab, Task No is a mandatory field, and the short description field is equal to Task No.

How can we have Task No and LI Description to get populated too?
