Helix Ext Amp: deactivate other switches, possible?

[Andree88]

Hi, I've a Helix floor + Engl Powerball II.

I use the Helix "ext amp" to change amp 4 channel via a stereo cable.

 

This configuration:

switch 1 -> channel 2 (if I press again it goes back on channel 1)

switch 2 -> channel 3 (if I press again it goes back on channel 1)

switch 3 -> channel 4 (if I press again it goes back on channel 1)

 

What I want to do, if it's possible, is to press switch 1 and then switch 2 but deactivating switch 1.

I need this when I play to go from crunch to lead then back to crunch without having to do a double tap on crunch switch (passing throguh channel 1 again).

So all I want is this: if I press switch 1 then switch 2 and 3 will be deactivated, if I press switch 2 then switch 1 and 3 off, if I press switch 3 then switch 1 and 2 off.

 

Is it possible? In stomp mode, not on snapshot modes if possible..

 

Here's a video of my Helix + amp. You see that if I pres switch 1, 2 and 3 they are still all on and I have to press twice to get them work back to the channel I need.

I hope I have explained it.
