Text overrides and translations

Translate content already created

Hi there,

I'm using H5P (v1.5) for moodle. I have been creating like thousands of h5p for months only in one language.
Now, I need to translate them all to the forced language of the course they are.
I decided to update to v1.19 because I read about a new setting to translate a given h5p to another language and that works pretty good but I can´t translate them one by one; that would be a never ending job.
Is there something I can do to make this jobs a little bit easier: cli script, something I can do programmatically, any function using parameters, etc?
