Docker for AWS with private subnets?

Hi, I´m using Docker for AWS cloudformation template but is it possible to setup this docker cluster with AWS private subnets ? Today you only can create docker cluster with public networks i ntemplate. I need to create a docker cluster that is private, including loadbalancer and docker instances…

https://docs.docker.com/docker-for-aws/

Is there any possibilities to create this or do I need to create docker cluster all manuelly ?

Thanks for a great product, Docker for AWS is quite complex and impressive work!
