Combining all API tags into one API name

I have a swagger yaml file with several different tags which tells the Swagger UI to create different sections. It makes the UI have a nice flow to it, however this presents a problem for swagger-codegen because I want all the REST calls to be accessible under one single API. These separate tags are interpreted as different APIs so the generated library is fragmented.

As a simple example, let "Pets" and "Accessories" be two different tags inside a yaml file.
"Pets" has the REST functions "getPets", "postPets" whereas "Accessories" has "getAccessory" and "postAccessory". Swagger-codegen will make a separate Pets API which you can call with "my_module.PetsApi().getPets()" and a separate Accessories API which you can call with "my_module.AccessoriesApi().getAccessories()". I would like to be able to call "my_module.MyApi().getPets()" or "my_module.MyApi().getAccessories()" -- where MyApi is like having an upper level tag that grants direct access to any of my module's various API's functions.

I find that this would simplify the syntax for my use case. This question is not specific to any language, I only used python syntax above to illustrate my point. Are there any other command options in swagger-codegen that I can use to combine all the APIs? Or perhaps a different way I can split up the REST functions on the swagger UI that won't mess with my swagger-codegen process?

(swagger-codegen version 2.2.3)

The issue names no files, tests, or entry points. Start by reviewing swagger-codegen 2.2.3's tag-to-API generation behavior and available command options; done means determining whether multiple tagged operations can be exposed through one generated API without disrupting Swagger UI grouping.
