How to add line number in pipe_mto.tmp ?

build-in report template
C:\AVEVA\Plant\PDMS12.0.SP6\PDMSUI\reports\templates\pipe_mto.tmp

I want to edit the report template, and run report,
the first column has the line number,and quantity use subtotal
as follows

Serial   Type  Detail                           Material          Tube  Quantity
                   Text                             Text
1  ELBO  ELBOW LR ANSI B16.9 BW           ASTM A234-WPB     0.00         1
2   FLAN  FLANGE WN ANSI B16.5 #300.RF     ASTM A105         0.00         2
3   GASK  GASKET RF 1.5MM ANSI B16.5 #300  SS & ASB          0.00         2
4   TUBI  PIPE SCH40 ANSI B36.10           API5L GR.B     1796.95         2
5   VALV  VALVE GLOBE ANSI B16.10 #300.RF  ASTM A216-WCB     0.00         1

it it impossible to add line number without pml programming

check report manual, but quantity is expressed base on subtotal
so you can easily add any additional infor in your report
