How to implement "Nats processor" with transport layer

[merlor]

Hello, I have a service with a business method
type Mysvc interface { MyFunc(res Request) Response }

Then I have a Nats subject from where I read the MyFunc's Request and a Nats subject where i have to publish MyFunc's Response;
then I have created a natstransport.Subscriber (with it's endpoint) and a natrtransport.Publisher (from whom I can get the Enpoint).
is there a way to combine them in order to have a "processor" (consume from a topic/subject and publish to another topic/subject) just using endpoint/transport layer without adding specific logic in MyFunc implementation?
