[FEATURE REQUEST] Volume Override Without Entering The Rosalina Menu

[ItalianNinjaa]

So I recently broke the volume slider on my New 2DS XL and I've been using the Volume Override option in the Rosalina Menu and I find it a bit annyoying to open the Menu every single time to change the volume, and i cant do it during online games since it wil kick me of timeout, so i suggest to add an option to configure button mappings to increase/decrease the volume by a certain amount (amount is customisable too), like R + Y + DpadUp/DpadDown to control it.

Thanks if you consider the request, it would help me and a lot of people who cant repair their volume slider/buttons and need to find another solution.
