Identify Lightning RecordEditForm in Aura Iteration

Question

I am using multiple Lightning Record Edit Forms in Aura Iteration and wish to uniquely identity the form when onerror is fired

1.Below is my Component.

<aura:iteration items="{!v.episodeList}" var="episode" indexVar="index">
  <lightning:recordEditForm onsuccess="{!c.handleSuccess}" onerror="{!c.handleError}" class="form1" aura:id="episodeForm" recordId="{!episode.Id}" objectApiName="Cable_Project_Season_Episodes__c">
  </lightning:recordEditForm>
</aura:iteration>

2.Below is my JS

 handleError : function(component, event, helper){
    console.log(event.target.name);
 }

I want to pass {!episode.Id} in name of RecordEditForm so that I can get the same in JS. But name, id, data are not supported by RecordEditForm
