How to convert just english subs via CLI?

[GFoley83]

I've got an MVK with some PGS subs. I'm only interested in converting the english ones. The command I've got that works for all is:
./SubtitleEdit.exe /convert "file.mkv" srt /ocrengine:tesseract /fixcommonerrors /removetextforhi

I've tried variation of "file.mvk*.eng.*" etc. but I've not had any luck. The PGS files seem to be labeled correctly in VLC and MKVToolNix.

Any help is appreciated.

I never let SE handle the MKV itself.
I first extract the subtitles with MKVExtract and then double-click the subtitle.

There shouldn't be a need to though right? Given SE can clearly handle the extraction.

I'm using https://github.com/ratoaq2/pgsrip for the moment, which handles this well.
