Multiple schemas per-endpoint possible?

Our use case is that in a Resource View we want to return either a single item for `GET /foo/pk` or a list of items for `GET /foo`. Not only does one schema have `many=True` and the other doesn't, but often we have different fields in them because listing may use a stripped-down schema for efficiency.
Right now if we want to declare this in the documentation we have to use different status codes, which is obviously not ideal:

(permission checks etc removed):
```
@marshal_with(Ref('_marshal_schema_class'), code=200)
@marshal_with(Ref('_marshal_schema_class_multi'), code=201)
def get(self, id):
"""Get single resource or list of resources."""
if id:
item = self._get(id)
return item, 200
else:
return self._query_for_current_user().all(), 201
```

Is there some way to support both schemas for code 200?
