It is very inconvenient that I have to use the preset customization for apps like safari, and can't just copy it from the global customization like other apps.

Most of the customizations I use are to reconfigure one or two buttons rather than the entire configuration, so it is also very inconvenient that when I want to change a button on global configuration, I have to manually change it in all other configurations which takes a lot of time

So, an ability to easily copy buttons across configurations (eg, easily copy what side wheel does from Global to Safari) would be very helpful.
