Can we merge asset lines in PA that are split by PRC: Generate asset lines

Hello,

We have a scenario where PRC: Generate asset lines created lines under incorrect assets. These lines are split among different assets (within same capital project and capital event) of same category. To fix this, we have unassigned the incorrect line items, manually created the missing assets and then associated the line items to newly created assets. But since these were split lines, when we assign to the correct asset we are seeing multiple asset lines. We would like all these lines merged to single asset line. How can we achieve this?
