WSDL URL for soapui mock service

We have an old web service which is defined to expose its WSDL via the URL pattern http://service/getorderservice.wsdl,
however when we try to use SoapUI to mock this service, it tries to use the following default URL for the WSDL: http://service/getorderservice?wsdl.
In summary, soapui mock service default wsdl url is: xxxx?wsdl, however our webservice wsdl url was defined as xxxx.wsdl

This make all our client tests fail because the WSDL is unaccessible. Any idea on how to config this in soapui?
