MGil’s suggestion is great and propably the fastest way.
To get more easy control over a song if needed, splitting up might make more sense.
You could do some basic settings in the complete gig-project. Then cut + delete everything but one song and save it to a new project to a dedicated song folder (backup function with minimizing events ticked). Go back to the complete project and repeat per song.
That way all songs share some general settings/vibe. If your mix evolves you can use track archives or channel presets to take it over to the other songs. It’s not fast. But it works.
