LV1 custom layer modes

How about adding “custom” in layer modes like this pict.
In case of simple operation, I don’t full fill 8racks in single channel and use a few FX and Mons.
I feel happy if I can operate it without changing layers.
It would be better, it is customizable.
Choosing Dugan shows only “ON” and group and occupy only 1slot would be good.
