Soft subtitles in MKV and MP4 container

[Robin_WH]

How do I encode soft subtitles into MKV or MP4 container using avidemux 2.6? I remember that in older version (2.4) there was interface for it with tracks, but I canÃ,´t find it anymore. Uncle Google gives either indeferrent or false (hardcode) results. So it is possible to softcode subtitles into mkv with avidemux 2.6 or not?
And if not, then WHY? And when will this function be available?

Soft like title.mkv and title.srt? .srt needs to be in the same folder as the .mkv video and have the same title.
If you need the subtitle inside the mkv video container, use mkvmerge GUI. Open the video with mkvmerge GUI and drop the required .srt file on to mkvmerge GUI and click [Start muxing].
In both cases above you should have a selectable subtitle in your video player.

Hard Encoded ASS/SSA subtitlefile could be found in Video Output: Filters only when not using Video Output: Copy. Re-encoding and burning subtitles in to images.

No. Soft like like:
Track1: Video stream
Track2: Audio Jap. dub.
Track3: Audio Eng. dub.
Track4: Eng sub.
Track5: Cz sub.
All in the one/same file/container either MKV or MP4

And I donÃ,´t want to use mkv merge, since I want to cut file for other purposes and it would be nice if Avidemux cutted soft subtitles along with audio and video stream. From your answer I get, that this function is apparently missing

Correct, softcoding was never there, only hardcoding.
Only way I know for now.
Process subtitles with Aegisub Advanced Subtitle Editor, merge sub tracks with mkv merge
