Is there a way to programmatically enable diagnostic tracing for a WSE web service client?

This is how it should be configured using an app.config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="microsoft.web.services3" type="Microsoft.Web.Services3.Configuration.WebServicesConfiguration, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </configSections>
  <microsoft.web.services3>
    <diagnostics>
      <trace enabled="true" input="InputTrace.webinfo" output="OutputTrace.webinfo" />
    </diagnostics>
  </microsoft.web.services3>
</configuration>

I would like to do this from code. Is this possible?
