can't link multiple audio to one video in the timeline

Hello,

I want to link multiple audio tracks to one video in my timeline but it does not work; I don't want to use the "command+G" but "command+L".

I read other topic so i need to precise that I am not talking about any sync process but just the action of linking multiple audios to one video in the timeline. When I select my tracks and clip then I link them it only unlink the video from its native audio... Impossible to link 2 or 3 audio track to one clip ....I think it may be a bug.

thank you so much for your help
