Is possible to specify existing server object for a route

openapi: '3.0.3'
servers:
    - url: 'https://example.com/api/v1'
      description: Legacy v1 server
    - url: 'https://api.example.com/v2'
      description: New REST API server
paths:
    /users:
        get:
            description: This is an endpoint for getting users list
            # other stuff

Is it possible to request changes to a specification, so I can add some sort of a key to indicate what endpoint should be used with the path?

For example:

servers:
    legacy:
        url: 'https://example.com/api/v1'
        description: Legacy v1 server
    rest:
        url: 'https://api.example.com/v2'
        description: New REST API server
paths:
    /users:
        get:
            description: This is an endpoint for getting users list
            servers:
                - $ref: '#/servers/legacy'
