Hello,
Thanks for contacting Databricks Support.
I presume you're looking to transfer files from external repositories to Databricks workspace. I'm afraid currently there is no direct support on it.
You may consider to use REST API which allows for the exporting and importing of notebooks. This could be used in a similar way to the CLI but may offer more flexibility if you're integrating this process into other automation pipelines.
