Is your feature request related to a problem? Please describe.

If there are multiple services with a same method. There will be a Request message generated for each service with the same name. Then the collision occurs because the package name is the same.

Describe the solution you'd like

Make package name depend on the service name.

Describe alternatives you've considered

Split Request message into another file and then import it. There might be a problem if multiple services have the same method name and different request parameters.
