can Zalenium support the integration with external docker containers?

[Babu216]

When you integrate zalenium with protractor/Selenium and trigger a test, Zalenium will spin up the docker containers based on your desired capabilities and these containers could support latest version of chrome and firefox which is a limitation, if you want to run on specific browser version, you should redirect your tests to the cloud platform like suaceLabs. To resolve this i've created my own dockers image and setup the selenium run time environment, but not sure how to integrate with Zalenium, is Zalenium integration with my docker image feasible ?
