How to merge keylegends in SGPLOT

[Claus_Stenberg]

Trying to get a a the symbols (scatter) and line (series) legends be merge together but can not get the group label on. Any ideas on how to solve this in a dynamic way? 
So in the below simple example I want to have F and M included in the legend label.  

proc sort data=sashelp.class out=class;
by age;
proc sgplot data=class;
scatter x=age y=height / group=sex;
series x=age y=height /  group=sex;
legenditem type=markerline name="symbol"/ lineattrs=GraphData1 markerattrs=GraphData1; 
legenditem type=markerline name="line"  / lineattrs=GraphData2 markerattrs=GraphData2; 
keylegend  "symbol" "line" /title="Sex";
run;
