Use the Batch Edit dialog

Batches in this window are listed in order from start to end. Each column divides into two parts, the current value and the changes to the current value. No entered changes are saved until Submit Changes is selected.

On successful submission, newly inserted or split batches or changes to volume or density for the existing batches will force a recalculation of the mass for the entire batch and associated fragments. All operations in this dialog will also be reflected in the calculation of the total mass at the segment level, section level and pipeline level.
