Check Number of Subtitle Tracks, mkvproedit

[Alieo]

Is there a way to check the number of subtitle tracks in a video using mkvproedit?

I'd like to create a batch file that sets the 1st subtitle track to default when there is more than 1 subtitle track.

I already have a batch file to set the 1st subtitle track to default but I need it to do this only if there is more than 1 subtitle track.

Is there a way to do something like "IF (videoSubtitleTracks > 1) { do stuff; }"?

Thanks
