[FFmpeg-user] How can I replace numbered sound tracks in my AVI ?

Doesn't anyone have any idea about these issues ?

I had no answer yet, but i'd like to remind you the main things i miss.

*First question*, is there an easy way for the user to mux an audio stream
to a desired stream number in the destination file.
e.g. : I want to mux one soundtrack to the 100th stream in my video.
Does it exist ? Is there any chance that this feature can be developed ?

*Second question*, is there a way for FFMPEG to modify an already existing
multimedia file ?
In other words : can FFMPEG *not* create a file from scratch when
adding/muxing/converting anything ?
Thank you all for your attention.
