Managing default settings and making the packaged game equivalent?

Hello! So I have tweaked some settings over time through console command to make things look the best for my scene.
However, other than setting the commands in the blueprint of each level (or gamemode for less repetition), is there a way to permanently set them? I cannot seem to find them in any of the .ini files.

Also I have found that when I package my game for testing, a lot of it doesn’t look right, especially refractions and reflections. How do I make sure that I get the same settings for the packaged game as in the editor?
