Francois,

such a module would not take too much development time as it is very simple.
But I personally would not see the need for such module. All functions can
be realized e.g. with the A-138c or the soon available A-138e.

But if there is sufficient inquiry we could offer such a module.

Best wishes
Dieter Doepfer
