The only on option Submaster work like an inhibitive scale but many people are using HTP Group Master to control Dimmer.
Ideally we need 3 options :

I assume Scale+ would increase the values independently from output values to 100% or a set value, whereas Scale- would reduce the values to 0% or a set value, both relatively to the output value?
Flash is already HTP to the underlaying output values and select should also be there already for the button options.
Yes correct… ;-)
