Referencing existing model in serverless yml file

Serverless Framework
1

Hello,

How can I reference a response model created already (in another serverless project). I need to reference this model in the documentation section as well as the http documentation section of my function call:

models:

     -

       name: "ClientErrorResponse"

       description: "4XX client error response"

       contentType: "application/json"

       schema: <<Here in documentation section>>

methodResponses:

              -

                statusCode: "200"

                responseBody:

                  description: "Response body description"

                responseModels:

                 "application/json": "my_resp.json"

              -

                statusCode: "400"

                responseModels:

                  "application/json": "<<HERE>>"
