At the moment, we do not have the feature to import the translation from csv file yet in this first version 1.0. Sorry for this inconvenience.
However, we're really aware of how this function is important to your need so we're trying to research and will bring this function in the near update for sure.
Stay tuned, please.
If you need some more help, please feel free to contact us via live chat or email us at firstname.lastname@example.org
