Can I update a mock service WSDL?

I think I am missing something here, but the WSDL has been changed and I would like to be able to reuse my responses and scripting I created last time around. The changes are minimal to the WSDL, mostly ordering but this client app is very particular about that.

Seems like I can only add new mock service? I added the WSDL to the project but it did not update the Mock Service.


Thanks!
