I want to set a Custom Function on my R6 Mark ii but none of the 5 possible functions are listed in the Custom Function section. Any suggestions? Ultimately I'm trying to the R6 to leave the display blank except when I go into the menu or when I playback a photo. I read this is a place to do that. Screen/viewfinder display is set to AUTO2. I don't use the display to frame a shot, I use the viewfinder.
