Actually it is a switch now, it is even labeled as "Switch".
That's another question that we can use anything as a switch, like channel values for example, but ATM in deviation every switch value should be interpreted as boolean.
What you describe more like the toggle definition of the main page config.
There you select a complex switch (not an actual switch state) and set bitmaps to the different states of that switch.
Even that behavior is more alike with the current virtual channel bundle.
If you make them depend on an analogue value, it will be hard to configure which level corresponds which trimset, not to mention that you won't be able to use a simple 3 state switch for it, like you do now, but would always need a virtual channel with complex mixing...
