Hi Benedikt,

in my opinion there is no way to translate the whole sitetree with one click. You can use Batch_actions to the translate the selected pages to the draft. But maybe there is a button, which will select all pages. I am not sure about that. If not, you can add easily a new Batch_Action, which will do this!

If there are any questions, how you can do this, please feel free to ask me.

Best,
Pascal
