MakeMKV for Windows: default setting subtitles (off)

[Tarnover]

Hi, is there any way to turn off the selection of subtitles by default in the Windows-Version?
As far as I could find out there is a way for the commandline version, but that doesn't help me.

Tools->General, select "expert mode"
Tools->Advanced, you can enter a string to control default selection of audio and subtitle tracks.

Information on what to PUT in that string can be found in the Advanced section here. I found one that works for me, but it's almost the opposite of what you're looking for, i.e., I want the subtitle tracks for English.
