The usual method is to define something new with a stereotype and an associated shape script.
This one draws a small, blue person, and includes a tagged value below it:
shape main
{
// Blue Person by Andy J;
fixedAspectRatio = "true";
setfillcolor(0,192,255); // (R,G,B)
setpencolor(0,192,255);
ellipse(70,-15,90,20); // (x1,y1,x2,y2)
rectangle(60,25,100,75);// (x1,y1,x2,y2)
rectangle(70,75,90,110);
setfillcolor(255,255,255);
rectangle(80,75,82,110);
rectangle(66,40,68,75);
rectangle(92,40,94,75);
setorigin("CENTER",0,0);
println(" ");
println(" ");
println(" ");
println(" ");
println(" ");
println("#NAME#");
println("#TAG:Stakeholder Type#");
println("<<#stereotype#>>");
}
