Separate setting of backlight activation for buttons and alerts!

I have noticed that the 945 firmware has no option to set automatic backlight for buttons and for alerts separately. There is only a single option to either have the backlight activated in case of both button clicks and notifications or have no backlight activation at all. I would prefer having two separate options to be able to set backlight to automatic for buttons but not for alerts as it is implemented in the Fenix 6 firmware! 

Is here someone from Garmin? Was this an intentional design decision or why are the two settings overlapping? Thank you!
