Mass edit, how to edit all selectable rows instead of one row at time in a gridColumn

a!gridField(
    data:local!data,
    columns: {
        a!gridColumn(
              label: index(local!labels, "id", null),
              sortField: "id",
              value: fv!row.id
            ),
            
            a!gridColumn(
              label: index(local!labels, "createdBy", null),
              sortField: "createdBy",
              value: fv!row.createdBy
            ),
        
    },
    pagingSaveInto: local!pagingInfo,
          selectable: true,
          selectionValue: ri!idDoc,
          selectionSaveInto: ri!idDoc
