Saving subtitles WITHOUT language-code

Since a few versions ago Kodi has changed the way updates work, and has removed the option to save subtitles without a language code (afaik).

Because of this, subtitles downloaded through Kodi’s subtitle addon can no longer be found by my DVR (which only opens subtitles if the file names match exactly).
My question therefore is:

Is there a way for me to setup Kodi to NOT include language codes in the subtitles when renaming them?

I hardly ever download any other subtitles but english ones, so I don’t really need the language code or the language-meta in Kodi.
