How to make Cougar's dogfight switch work with MMjoy2

I have TM Cougar set wich I have modifyed with Leonardo Micro Pro pcb's with use of MMjoy2. How can I have the dogfight switch work as it used, with three positions? The Middle position is the hard one for me. Let's say that there is three buttons 1,2 and 3. 1 and 3 is outer positions and 2 is the middle postion.I did manage to put the settings of MMjoy2 so that when I push the button to pos 1 it produces button 1 press. When pulled back (to the middle), it produces button 2 press. This is OK. But I can't have it work from pos 3 to pos 2(middle). How that can be done? Or is it impossible task with MMjoy2 only?
