I don't think so. MakeMKV is just for getting the bits off the plastic disc and into a file without the DRM. What you do afterwards is up to you.
Personally, my setup can display the PGS subtitles that come off the disc just fine, so I leave them alone.

Re: Help with subtitles
That is a limitation of a lot of players for automatic inclusion of separate subtitles. Some want the language included in the file name, too.
It is possible to include the subtitles IN the movie, but MakeMKV doesn't do that. Handbrake is one tool that can do that, assuming you also want to shrink (usually) the video at the same time.
