The way we're supposed to approach this in Studio One is by creating a template with our preferred settings. I have one called "New Empty Song".
First, create a new song with your desired song settings. Then go in and configure the windows and per-song settings (like auto-scroll, snap to grid, Audition Notes, etc etc) just the way you want for a new project.
Then save it as a new template by going to File -> Save as Template. Call it whatever you want, but something like "New Empty Song" or "Empty Song Template" will help you identify it later when you create more templates.
All you need to do now is open this template every time you want to open a new empty song and your preferred "starting point" for a new session will be preserved.
