Databricks Asset Bundle (DAB) from existing workspace?

[dbx_687_3__1b3Q]

Can anyone point us to some documentation that explains how to create a DAB from an EXISTING workspace? We've been building pipelines, notebooks, tables, etc in a single workspace and a DAB seems like a great way to deploy it all to our Test and Production environments. All the documentation and videos I found so far demonstrate creating a new DAB from inside VSCode. Is our use case currently supported by asset bundles?

The Last link posted no longer works. Also, the commands seem to have changed in the Databricks CLI. I see no `bundles` command, only `bundle`....and that command has no `create` option. Is there no way to convert a dbc file to a bundle any more?
