Can't add r_visibility console command to menu?

[wanisea]

When playing the DOOM CE (https://www.moddb.com/mods/doom-ce) version, the map was too dark, so I adjusted the brightness with the r_visibility command to get a lighting effect similar to the original.
It's inconvenient to have to enter a console command every time you run GZdoom, so I hope it's added to the menu.

Adding r_visibility to menu won't make it saved between games. You may want to use an AutoExec file which sets r_visibility to the value you want.

Indeed, we will end up with overgrown menu if we put all debug CVARs to it.
