Aws-sam-cli: Api inline swagger with $ref to external file

[chestongo]

I want to use an additional external swagger file in my swagger.yaml file.

ServerlessApi:
  Type: AWS::Serverless::Api
  Properties:
    DefinitionBody:
      Fn::Transform:
        Name: AWS::Include
        Parameters:
          Location: ../../api/swagger.yaml

paths:
  /company:
    $ref: ./routes/company/swagger.yaml

How can I do this using SAM?
SAM doesn't upload the additional file.

@chestongo SAM currently uploads original swagger files and doesn't import additional swagger files.
Transferring to aws-sam-cli

Can you please share your folder structure? As in where are you keeping the additional swagger file?

But what i want is:

├── api
│   ├── models
│   │   ├── car
│   │   │   └── swagger.yaml
│   │   ├── company
│   │   │   └── swagger.yaml
│   │   ├── empty
│   │   │   └── swagger.yaml

--- etc ---

│   ├── routes
│   │   ├── car
│   │   │   └── swagger.yaml
│   │   ├── company
│   │   │   └── swagger.yaml

--- etc ---

│   ├── swagger.yaml
│   └── templates
│       └── swagger.yaml

However, from @ShreyaGangishetty reply, it is currently not possible. If you have many api endpoints, with configurations, you have to store all the definitions in one huge swagger file.
