Changing the resolution of JUST the character selection screen

[Eshaton]

Im on an ultrawide curved. Have the game set up fine when I play, However the character selection screen always goes full screen at my desktop resolution. Any way to tweak the INI to change the resolution of the character selection screen only. IN game is set up perfectly took a bit using viewport command to do it. So I dont want to mess that up.

Anyhow thanks in advance
