Use github container registry as private registry

DockerHub has gotten needlessly expensive so I’m trying to architect a switch to Github Container Registry (in beta). The only way to authenticate is currently using a Personal Access Token (Pushing and pulling Docker images - GitHub Docs). Does anyone know whether Aptible’s private registry username/password convention can be adapted to this use case? Or if not, if Aptible has any plans to add this option at some point down the line?

In the GitHub docs, they given an example of logging in via docker login using your github username and the personal access token as the password. You should be able to use the same values for Aptible’s private registry username and password, because it relies on the same registry authentication mechanism as docker log

"APTIBLE_PRIVATE_REGISTRY_USERNAME=$GITHUB_USERNAME"
"APTIBLE_PRIVATE_REGISTRY_PASSWORD=$GITHUB_PERSONAL_ACCESS_TOKEN"
