Stable Dots on Slider Question

Hello,
I am want to add a question to a survey where the respondent sees their response to a prior question asking for the median value, the true median value, and the 90th percentile value. I have figured out how to add two dots to the question in addition to the default slider value (the median value) using Java Script, however I have not figured out how to make one dot a fixed value and not dependent on a previous question. I also need the respondent's dot to be a different color from the 90th percentile. How can I do both of these things? I've copied my current code below.

Qualtrics.SurveyEngine.addOnReady(function()
{
   var s = ("${e://Field/RentLabelArray}").split(",");
   var lpos=[];
   for(var i=0;i    jQuery("th.ylabel span span label span").each(function(){if(jQuery(this).text()==s[i]){lpos.push(jQuery(this).closest("tr").index())}});
   }
   console.log(lpos);
   var v = ("${e://Field/RentValueArray}").split(",");
   var n=7200;
   var totalwidth = parseInt(jQuery(".track").css("width").replace("px",""));
   var u = ( totalwidth -20 )/n ;

   for(var i=0;i        jQuery(".horizontalbar td.BarOuter:eq("+lpos[i]+") .track .handle").clone().insertAfter(".horizontalbar td.BarOuter:eq("+lpos[i]+") .track .handle").attr({"id":"customhandle"}).addClass("customhandle").css("left",v[i]*u+"px");
   }


   /* Add in 90th */

   var s = ("${e://Field/RentLabelArray}").split(",");
   var lpos=[];
   for(var i=0;i    jQuery("th.ylabel span span label span").each(function(){if(jQuery(this).text()==s[i]){lpos.push(jQuery(this).closest("tr").index())}});
   }
   console.log(lpos);
   var v = ("${e://Field/RentValueArray}").split(",");
   var n=7200;
   var totalwidth = parseInt(jQuery(".track").css("width").replace("px",""));
   var u = ( totalwidth -200 )/n ;

   for(var i=0;i        jQuery(".horizontalbar td.BarOuter:eq("+lpos[i]+") .track .handle").clone().insertAfter(".horizontalbar td.BarOuter:eq("+lpos[i]+") .track .handle").attr({"id":"customhandle"}).addClass("customhandle").css("left",v[i]*u+"px");
   }

});
