In MMJoy2, there are any posibility to use one interruptor (on/off) to work like a push button?

I want use this:




Now, i have 3 pulsations on 4,5 and 6 button of MMjoy, but, permanent, not like a pushbutton.

I need 3 positions like FW190 in DCS Series,

Magnetos:
1 position: off
2 position: magneto 1
3 position: magneto 2

Thanks....
