Why testrunner report files don't store request body when using "Run TestCase" type ?

Hello,

When executing some SOAPUI tests having steps of type "Run TestCase" using testrunner, why the report files generated do not contain the body of POST requests ? is there an option to log them ?  Into the UI, I can see the request body in Raw request.

Example from UI (Raw request):

POST xxxxxxxxxxxxxxxxxxx/xml HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: application/xml;charset=UTF-8
Content-Length: 1627
Host: xxxxxxxxxxxxxxxxxxx 
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soap:Header>
      ...

Example from testrunner report file:

----------------- Properties ------------------------------
