Hi,
It's not available yet in v6. Also the Falang integration is not added to v6 yet.
For now you can create a seperate list for each language. According to Acyba that was also best practive in v5. Besides that it's needless to say that we still miss some language) features. Acyba will bring it back for sure. Unfortunately it's not possible to bring back all v5 features at once.
