Creating internal rabbitmq exchanges

With the rabbitmq provider is it possible to create an exchange with the internal bit set?

The the declare exchange method in the rabbitmq API allows you to set an internal flag on creation of the exchange - https://www.rabbitmq.com/amqp-0-9-1-reference.html#class.exchange

But this seems to be missing as an option from the exchange resource in the terraform provider - https://www.terraform.io/docs/providers/rabbitmq/r/exchange.html
