You are correct, this is currently unsupported by TabCmd and the REST API. The only way to do this programmatically is to mimic Tableau Desktop's behavior (it uses a different, undocumented API). This would require you to reverse engineer those APIs and would be unsupported.
I have mentioned this to the API team at Tableau and they are aware of the limitation. Hopefully it will be added in a future version.
