Hello,
I’m sorry. Not for now.
But some users are asking for a similar feature. Please tell me if the following approach would help you.
What do you think of a new field on settings page where you can add downloadable files, similar to the downloadable files section on product page? After that there would have to be a new “regenerate button”. It would search for orders containing products with these downloadable files and would regenerate only these orders. What do you think?
