Possible more options for 'Solid Reactive' backlight mode ?

[MrPhntm]

Hello !
First, apologies if I make this request in the bad place…
Little time after the purchase of my first keyboard (GMMK Pro in French ISO) I used VIAL which is enough for almost all my needs. But I was wondering if it was possible to customize some features for the backlight.

I use "Solid Reactive" for my backlight, and I was wondering if it's possible to choose the color when I press a key ?
For instance, I currently have some green-ish blue, and when I press a key the backlight is pink / purple.
It's possible to customise that other color (purple/pink one) like I change the general color backlight ?

It could be a particularly interesting option for customizing even more our keyboard.

Thanks in advance.
