Can I have more than one comments type attributes (custom) in RTC work item

Hello All,

I want to log a few multi-line attributes. Can I have more than one comments type attributes in RTC defect work item?

If yes, how Can I do it. There is no Comments attribute type available in the drop-down list when I add a new attribute.

If no, is there any other way to log an attribute? I could not find a way to get the attribute previous (original) value in Calculated Valuess script. My script like this:

dojo.provide("example.calculated.AnalysisLogProvider");
dojo.require("dojo.date.stamp");

(function() {
  dojo.declare("example.calculated.AnalysisLogProvider", null, {

    getValue: function(attribute, workItem, configuration) {
      var sAnalysis = workItem.getValue(WorkItemAttributes.Analysis) + "\n";
      var sAnalysis_Log = workItem.getValue(WorkItemAttributes.Analysis_Log) + "\n";
      var sDate = dojo.date.stamp.toISOString(Date.now(), {milliseconds:true, zulu:true}) + "\n";
   return sDate + sAnalysis + sAnalysis_Log;
      }
    }
  });
})();

workItem.getValue(WorkItemAttributes.Analysis_Log) alway get the current value. That means it will comtains some repetition of the value entered in Analysis becuase the script continuously executed.

Thanks.
