Hi, I want to add a DockerRegistryCredentials block to the base-job-template. At the moment I use this in the json:

"registry_credentials": {
		...
        "default": {
          "$ref": {
            "block_document_id": "<id>"
          }}}

Is there a way to specify the block name? I have tried

"$ref": {"block_document_name": "<name>"}

and

"$ref": {"block_document_name": "docker-registry-credentials/<name>"}

but were accepted be

work-pool create

but let to an empty entry in the UI.
