Display remaining filament as a percentage

Would it be possible to add a percentage display for the remaining filament quantity? Currently, the remaining filament quantity is displayed as a bar, which is invisible when using white filament. An easy-to-read percentage display would be GREAT! If you could also create a remaining quantity display for alternative rolls (i.e., insert the roll, enter the quantity on the roll, and Bambu calculates the remaining filament), I would be very happy!

Thanks
