Hey Peijian,
That's a super good question.
Safest solution is probably to set up a Wwise project with the overall hierarchal structure and hooks, and don't change that structure while you're working remote. So here's what I would do...
1. In your Project Explorer, set up your hierarchy with Sound SFX or Random Container objects. If there's just the slightest chance you'll be using multiple variations for a sound, use a Random Container, cause you can always have a Random Container with just one variation.
2. Create corresponding Events and SoundBanks. Preferably with a solid naming convention, so that any party will know what it is.
3. Hook it up in Unity. If you are using Wwise-types and you're not the one to add that in the scripts, make sure they know how to validate the properties.
Then as you work remotely, the key is not to change the related structure of events and associated containers, but just update the contents within those containers.
Cheers!
