Pass QAComplete current configuration value to SoapUI TestRunner

I am on a trial version of QAComplete 10.0 and I made it through the new feature of executing SoapUI tests from QAComplete. I currently have multiple configuration records and multiple test libraries where each test library will be executed for multiple configurations.

However, in the Test Library under the Automation tab I am trying to use the Custom Args to pass current configuration value to SoapUI testrunner so that SoapUI can obtain the configuration value and execute accordingly. Something like this -Pconfiguration=${configuration name}

I need to find out how to refer to the current configuration name being executed
