Unfortunately, due to heavy workloads, I have not been able to add that functionality yet. I have already started to re-code the entire project but it's not at a point yet that I can push anything up. You can look at the available hooks to attempt this yourself.
I saw you mentioned multilingual support in the Readme. Is this something you have worked on?
I need to migrate a client's multilingual site from Drupal 7 to WordPress. On the WordPress side we will be using Polylang.
Even if you have some rough code it could help get started.
