Currently, it is possible to send events to modules with ID = Option ID as seen in the UI, like you would do with controllers. This is undocumented by the way, I think you should add it to the manual
Unfortunately, it seems that get/set controller min/max value, get controller name etc. don't work. The offset = 0x70 also collides with FMX controllers, since it has 0x77 controllers at the moment.
