I really really really want this because this is easily one of my top annoyances with Unity Hub. Let me explain this a bit. Right now when you hit New project button, it'll suggest you to use parent folder from your last added/new project's root. This is not something I want at all and I don't get why Unity came into conclusion this would be a good thing. Now I constantly end up cleaning up things right after project creation as I always forget Hub does this. Because of this design, I often end up having new projects in totally random locations, often inside some cloned git folders which have the actual sample project further down their path. This happens because Unity Hub defaults the new project path to the last added projects parent folder which is NEVER what I'd want to happen. Instead I just want to place new projects under same parent folder and not give Unity Hub any power on overriding my default location behind my back. This would be easily fixed if Unity would let us put generic root folder for new projects (like done on most tools like this).
