combining switches for 6 outputs on one channel

I just got a pixhawk px4 FC and am trying to set up my quadcopter with it. In order to select the flight modes one of the tutorial videos used a Taranis tx that allowed setting up a 2-way switch in combination with a 3-way switch to achieve 6 values on one channel allowing the selection of 6 flight modes. I'm pretty sure this can be done with deviation but what I've tried so far hasn't worked. Could someone please help me out with the code in the model.ini file or the steps to set it up on the transmitter itself? Much appreciated.

I remember there being an ini on this forum for just that purpose bud, try searching the site with google and seeing what pops up

Thanks Harry, found it. Will give it a shot and see what happens. Matthias takes a bit of a different approach but it might actually be better for what I have in mind.
