Joining multiple video-only and audio-only files with VLC

How to do that?

I Can Split multiple video files to video-only and audio-only part via multiple file selection and convert/save...
When i try the same for joining multiple video-only and audio-only files, via Play another media synchronously, and use multiple files for both lists, second file list is always play from beginning from every file from first file list.
Fist file list is: File selection. Second file list is: Extra media.
Is it possible to do it somehow?
Thanks

To clarify, I want to join 1 by 1, video only part and audio only part join to normal video, and repeat that to whole file list
