HELLO adobe premier when synching audio how can we as functioning editors designate which track moves

When syncing audio how can we, as highly functioning editors, who would like to continue to use Adobe and NOT move to Davinci... designate which audio track moves. There should be a designation for master Audio, it cannot be that hard.

I also noticed that Premier will ignore grouped selections and randomly move what it feels like moving, nullifying a group,  Example, I have V1, A1, A2, A3 synced and grouped.  I then want to add a 4th synced audio channel.  In doing this Premier, ungroups A3, and randomly moves V1, A1, A2, to match the location of A4?

In what world would this EVER make sense?  FIX IT...PLEASE!  WE MUST BE ABLE TO DESIGNATE WHICH TRACK MOVES, AS WELL AS NOT LOSING GROUPED SYNCED CHANNELS, ANYTHING LESS IS SUBSTANDARD.  Or we switch to Davinci?
