openapi-generator: go-echo-server. How does this handle adding/changing API?

[eatwithforks]

Currently, when I run `openapi-generator generate -i openapi.yaml -g go-echo-server', it generates a set of handlers, models, and other files.

But when I make code implementation changes to the handler's scaffold functions, I want the code written to stay and not get overwritten when I add a new route with the same tag.

Is there a way to "merge" the new functions to the handlers / models without erasing the existing implementations?
