Responses in separate files

Hi,

I have a project that from WSDL and XSD creates a mock service.
I have several responses for one service.
For the service I created a script that dispatches different requests  to the respective responses.
From time to time I receive update of the WSDL or the XSDs and I have to regenerate the project - delete/create new. However I delete the responses and the scripts.
Is there a clever way of updating the service ?
My first versions of the question was "Is there a configuration setting that responses and services are created in a separate files?", but maybe you could suggest different solution.

Thanks,
Todor
