Is it possible to change player settings by default?

Hi there,
I’m trying to adjust some game player settings such as r.ShadowDistance or some other stuff, and accually it worked by entering this command in cmd bar. But all settings seems to be reseted after proiject get closed, which means I must adjust all these things again next time I open my project.

 I've tried to find these detail setting in Project Settings but they're not there. Also I've modified those values directly in Engine\Config\BaseScalability.ini and it seems to be useless.

 So what should I do? Any help could be many appreciated!
