How to format NLog exception output to get a line separator?

Question

How to get the below output format using NLog error logging; A line separator between each exception log. like;
2017-06-19 16:53:20|SessionVal| Error message| Exception's Message | StackTrace _______________________________________________________________________________________ 2017-06-19 16:52:10|SessionVal|Error occured while executing the procedure. |Procedure xyz expects varchar(20) @ParameterName.|StackTrace....

Current NLog configuration;

<nlog autoReload="true" xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <targets>
    <target name="logfile" xsi:type="File" 
   layout="${date:universalTime=false:format=yyyy-MM-dd HH\:mm\:ss}| 
   ${aspnet- session:Variable=SessionKey} ${message} | 
   ${exception:format=type,message,StackTrace}" 
   fileName="${basedir}/App_Data/Log/ 
   ${date:universalTime=false:format=yyyyMMdd}.log" />
   </targets>
  <rules>
    <logger name="*" minlevel="Info" writeTo="logfile" />
  </rules>
</nlog>

Update: @Amy, are you telling like this;

If I understood correctly then according to this thread https://github.com/NLog/NLog/issues/1713 header is logged only once per file. I need line separator between each exception log entry. — c-sharp, Jun 20 '17 at 13:43
That's an option more of tedious, but was looking if there's any builtin feature to get it without changing in hundreds of different places. — c-sharp, Jun 20 '17 at 13:58
No, this isn't built-in, and no, you wouldn't have to put it in hundreds of places. Your layout is right there in your NLog configuration. — , Jun 20 '17 at 14:01
@c-sharp You can also use ${newline} https://github.com/NLog/NLog/wiki/Newline-Layout-Renderer — Rolf Kristensen, Jun 20 '17 at 17:14

According to the asker of the question this is a solution:

layout="-------------------------------------------------------------- 
    ${newline}${date:universalTime=false:format=yyyy-MM-dd HH\:mm\:ss}| 
    ${aspnet- session:Variable=SessionKey} ${message} | 
    ${exception:format=type,message,StackTrace}"
