Add an external audio track in the encoder

Hi,

I waited a long time and was lazy to write this, believing that this feature would appear soon. If I have a file and I just want to replace the sound in it without opening Adobe Premiere, then I don't have that option right now. I ask you to add this in new versions along with the function to copy any track without transcoding, as I wrote earlier. So far, I have to use a lot of additional tools to do the work that could be done in one program.

Thank you
