   Would it be possible to personalize connection by changing 
[get_sqla_engine](https://github.com/apache/incubator-superset/blob/e53f3032bb2cc03019dec1b5eab49911801eab3a/superset/models/core.py#L590)
 to something like the following code snippet.
   
   
       def get_sqla_engine(self, schema=None, nullpool=False, username=None):
           extra = self.get_extra()
           uri = make_url(self.sqlalchemy_uri_decrypted)
           params = extra.get('engine_params', {})
           if nullpool:
               params['poolclass'] = NullPool
           uri = self.db_engine_spec.adjust_database_uri(uri, schema)
   
           # Inject user name into engine URL
           uri.username = username
   
           return create_engine(uri, **params)
