[Cerrado] Translating WooCommerce downloadable products

Our customer needs to translate WooCommerce downloadable products.
That means, attaching a different file for each language.
The use case is to sell access to PDF files and since PDF files are language specific, this requires us to select a different PDF file for each language.
But when we connect multiple products from different languages, we can't edit the "Downloadable files" for the translations.
How can we solve this problem?
Currently we work around the problem, by not connecting them via WPML.
