Background of the issue:
I am developing a site and need to duplicate translated content from English to Dutch into another language variant, Belgian Dutch (nl-BE). I do not need this to be automated but want to know if there's a manual way to duplicate the existing translation without retranslating everything.
Symptoms:
I have tried using the WPML Translation Management Module and looking for a 'Duplicate' option in the WPML Translation Editor, but neither approach was successful. I also checked WPML settings for an option to use the same translation for Dutch and Belgian Dutch but found nothing relevant.
Questions:
What is the correct way to manually duplicate existing Dutch (nl-NL) translations to Belgian Dutch (nl-BE)?
Does this have to be done entirely manually, or is there a WPML feature that facilitates the duplication process?
If duplication is not possible, what is the best practice for managing this language variant efficiently?
