Hass.io with docker network

I want to install hassio via the installer (https://github.com/home-assistant/supervised-installer), but I want to have all those docker container in a specific docker network I already created, to avoid port overlapping etc.
Is that possible?
I found this file so far https://github.com/home-assistant/supervised-installer/blob/fc0809a4c13541d18092e10eff0674e6c93778e1/files/hassio-supervisor#L27
but then it would be missing for the managed containers, right?

Thank you
