Single DockerHub credentials for multiple private images

When I was using AWS ECR as docker registry it was possible to set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables in project settings/context and avoid credentials duplication in the config file.
Now I’m using DockerHub and I have to specify auth section for every image, which is annoying.
We are using 20+ private images, is it possible to set single credentials for project/organization?
