SQLAlchemy temporary table with Declarative Base

Is it possible to use __table_args__? See http://docs.sqlalchemy.org/en/latest/orm/extensions/declarative.html#table-configuration

class Tempo(Base):
    """
    Class for temporary table used to process data coming from xlsx
    @param Base Declarative Base
    """

    # TODO: make it completely temporary

    __tablename__ = 'tempo'
    __table_args__ = {'prefixes': ['TEMPORARY']}

    drw = alc.Column(alc.String)
    date = alc.Column(alc.Date)
    check_number = alc.Column(alc.Integer)
