How to suppress the Nonce and Created element in WS-Security header

Hi,

    I'm using SOAP UI 5.1.2 to test a WS that I have implemented with WS-Security.  I have configured the WS-Security configuration at the project level to generate Username token with Password Digest but without any Nonce or Timestamp (because the WS implemented does not expect Nonce).  However, the SOAP message generated is always containing Nonce and the timestamp in the SOAP header.  Is there a way to suppress them?
