My team does type of action for our dual acting solenoid.

bool isReady;
bool Piston;

isReady = true;
Piston = false; 


if (DriverJoyStick.GetTrigger() && isReady && !Piston){
		Piston = true;
		isReady = false;
} else if (DriverJoyStick.GetTrigger() && isReady && Piston {
		Piston = false;
		isReady = false;
} else if (!DriverJoyStick.GetTrigger()){
		isReady = true;
}

Where when you press the DriverJoystick Trigger and release it, it toggles the Boolean HalfSpeed. The Boolean you can set later in your code. We use it such as.

if(Piston){
	piston.Set(Relay::kForward);
} else if (!Piston){
	piston.Set(Relay::kReverse);
}
