How to add reference line to each bar in SAS GTL

[Pepsimax2]

I am trying to add a reference line to each bar in SAS GTL. I know I have target= in barchartparm but I need to customize the line to dashed, which I can not find anyway to do that in barchartparm.

I tried scatterplot and symbolchar to overlay a "DASHED LINE" unicode but the issue is the unicode I used is not vertical centered. It cannot be placed right at the data point. I tried vertical offset to fix it then another issue is in the legend, the same symbol char was used but if I changed the size of the symbol in legend it resulted in so much space in the legend box then the figure became too long.

I wanna ask are there some other way to get around this? or some magical normal dashed line unicode that I can use? I searched so many some just gave me a empty box which I do not understand why.

Thank you so much for your help!

Here are the part of the code:

proc template;
   define statgraph &st.&yr.&pp.TopBox;
   BeginGraph / DesignWidth = &Height.in ;
   
   symbolchar name=line char='2508'x /voffset= 0.39 ;
   symbolchar name=linelengend char='2508'x /voffset= 0.3;

   discreteattrmap name = "line";
      Value "1" /markerattrs=(symbol=line color=black size = 0.8in);
 
   enddiscreteattrmap;
   discreteattrvar attrvar = drawline var = line attrmap = "line";


    legenditem type = marker name= "XXXX" / label="XXXX"
                                            markerattrs = (Symbol = linelengend Color = black Size = 0.4in);

    Layout Overlay / XXXXX ;
       /* Create Bars */
 BarChartPARM x = XXXX   y = XXXXX / Group = PlanColor
                                         GROUPORDER= reversedata
                                         GroupDisplay = Cluster
                                         CLUSTERWIDTH = 0.5
                                         Orient = vertical
                                         DataSkin = &DataSkin. 
                                         /* DATALABEL = XXXX*/
                                         /* DISCRETEOFFSET = -0.2*/
                                         datalabelattrs=(size=10 weight=bold)
                                         ERRORLOWER = Lower_CI
                                         ERRORUPPER = Upper_CI
                                         /* target = XXXX*/
                                         ;

 ScatterPlot x = XXXXX    y = XXXXX  / Group = drawline
                                            GROUPORDER = reversedata
                                            GroupDisplay = Cluster 
                                           /* DATALABEL = XXXXX*/
                                          ;

DiscreteLegend "XXX" / Border = Yes
                        ValueAttrs = (Family = "Calibri" Color = Black Size = 10)
                        ;

It is easier to help if you post your current code with sample data and output.  Also the SAS release number.
