How did you specify the two VSCode windows each set with different project directories? I wanted to do this too but the "Open with" drop-down in "Advanced" settings only showed four apps, none of which were VSCode.

I'd also love to be able to give it a window of tabs in Chrome or Firefox and have it open all of those in one window. Perhaps there's already a way but it wasn't obvious to me.

EDIT: I kept reading the comments and found the VSCode solution. You add VSCode first and then specify a folder to open.
