Change service

Is there a way to change the service (name) on a RESTtest request? I had to manually create the binding because the WADL was not available and now I wish to add the WADL, but I need to change the service on the REST test request. IF I remove the service from my project it deletes my tests. I tried changing it through the project xml file, but it deleted the tests also. I cannot change the service through the REST test request properties. There's got to be an easy way to do this that I'm not aware of.
