Testing Shared Spatial Anchors during dev

Hello everyone, 

I am building an app that requires shared spatial anchors, thus it is a multiplayer app.  So I have two questions:

1- Quest development requires using Quest Link when trying the app in Unity, which is fine, but when I want to test in multiplayer, I often use ParallelSync and open two Unity editors. But it seems abit difficult to do the same now on the same PC connecting 2 Quest devices. Any suggestion around this? 

2- Sharing spatial anchors requires App ID, which seems to only work after you build the app and upload to App Lab, this will be incredibly time consuming, is there a way to use and share spatial anchors using Unity Editor and Meta Quest Link without building every time? 

Thanks alot everyone.
