To export to Word - problem with language

Hello, (Adobe DC pro, PC, windows 10, with Office 2016)

Here is my problem : I export pdf to word doc. My document are not in english but in french.

When I open Word document, the language is in english. So there is problem with spell check... every time.

I have to change language in word document (every time).

Of course, that's not difficult to change, but it's every times - and it's very long with word documents with comments (i.e. Insert comments).

I'd like to export pdf to Word document, in french, every time!

Thanks.
