SOAPUI how to use static mock data in mock service and back

i want to have the possibility to use static mock data from mock service in SOAPUI for some services and for other services i want to use the mock data at the back end in the same project. is there any way to do that with SOAPUI or do you have any ideas how to do that? My back end is on the port 8080 and the Mock data on the Port 8081.

Thanks
