Adding NTLM v2 support in SOAPUI Proxy Settings (and others)

Would be nice if SOAPUI could have support for NTLM v2 for the Proxy Settings.
Default Proxy of my company is configured to accept only requests identified with NTLM v2.
So, impossible for SOAPUI to reach a service available outside our intranet because NTLM v2 is not supported by SoapUI in the Proxy Settings.

Thanks a lot.
