WS Security Signature with Symmetric Key

Hello,

I have web service that requires to use same Symmetric Key for both Encryption and Signature.

By using WS Security config , in the  Encryption , Symmetric Key is generated using provided public key from keystore.

The main problem is with Signature:

Is it possible to use the generated Symmetric key for Signature in SOAPUI?

and in general, is it possible to use Symmetric Key in WS Security Signature in SOAPUI?
