All variants - same keyboard bindings?

[funkyfranky]

Why do all variants of the Gazelle have to share the exact same keyboard bindings?

 

This is a big waste of my physical hardware as buttons that are used only on the L cannot be used for something else in the M and vice versa.

 

Any change that could be improved?

 

This does not seem too complicated as other modules for which different variants exist all have their own entry in the controls options (e.g. C-101CC and C-101EB, L-39C and L-39ZA).
