FN Layer key press fallback to main layer if not remapped

[NotLegish]

Is your feature request related to a problem? Please describe.

Unable to use main layer keys while using FN layer, even when the key I am trying to use is not remapped on the layer.
Lets say I have only remapped the media keys in the FN layer. I am running in a game and I want to change my music volume, I press "FN" + "PAGE UP" (Increase Volume), but now I want to turn in the game by pressing the "D" key, unfortunately this will not work because I am still holding the FN button, since I have not reached my desired volume.

This is a feature I miss from my non wooting keyboard, even though this does not happen very often but whenever it happens it is annoying.

Describe the solution you'd like

I would like if the keyboard would check if the key being pressed is remapped on the layer, if the key is not remapped it would fallback to the main layers key.

Seems you may be able to nest FN layers, for those I would like it to check if the key being pressed is remapped in the layer if not advance to the previous layer until main layer.

This could be a setting in the layer if it should fallback to the previous layers keys.

Describe alternatives or workarounds you've considered

Manually remapping the keys on the FN layer that are not remapped to the same key as on the main layer (A -> A, B -> B) would probably work, but that is likely gonna take a while to setup.
