I see that you can enter your name in player 1 or click player 1 to enter your name, is there any way to configure something in settings so that it will automatically fill it?

It is always filled automatically if you're not a mod for the game (as only mods are allowed to submit runs for others).
For mods there is no setting to fill it automatically. Considering it's only one click to fill it I don't think it's really necessary to add either.

I just leave it blank and it automatically does it.
