Academic Theme: Multilanguage settings, using same folder for translated files

Hello,

In academic theme documentation, for multilanguage, the content directory is separated based on directory. I do not want do that. Hugo multilanguage documenation states with leaf bundle setup the posts translated different languages can stay in the same folder. File names can be post-file-name.en.md post-file-name.fr.md etc. The translated files are distinquished by file name suffixes not by location. Is it possible to in Academic Theme?

Thanks in advance…
