edit multitrack audio and subtitles

[frank10]

I have an avi with 4 audio tracks (2x AC3 6ch) and 4 subtitles track.
I would like to cut some scenes and keep all audio and sub without recompressing.
I left 'copy' on both A/V, put 'mkv' as output and I got the 4 audio tracks but no sub.
Also the 4 audio tracks, lost their names becoming "Undetermined (Audio1) default" etc.

Is it possible to keep names of tracks and the sub?

btw: I use latest r8381.

Is there a way to keep also the subtitles?

I don't no any way to do this but would like to see it as well.

subs are discarded at the moment
Not easy to add that feature
