Viper 690XV, Aux configuration possible?

Hi!

On the remote transmitter of the Viper 690XV car alarm, you only have possibility to adress two different additional output channels:

Channel 2 -> pressing "AUX"
Channel 3 -> pressing "arm" and "disarm" button at the same time

As Channel 2 (AUX) has a standard configuration to a 1,5 second timed output with "validity", is it possible, to configure this channel/button to immediately triggering the output and/or to make it "latch"?

I assigned my windows to this channel but it's not very comfortable to control window roll up/down with an output signal that has a delay of 1,5 seconds.
Furthermore, I installed a 450T channel expander to open my trunk with the same output, but this way, opening the trunk will last about 5-7 seconds (two times 1,5 seconds delay + waiting for the 450T feedback signals + trunk opening)

I tried to install the windows and the 450T channel expander to channel 3, but this doesn't work for me, as

- channel 3 already covers the remote of my auxiliary heating, which needs a "latch" output
- pressing two buttons at the same time for opening windows or trunk is not very comfortable!

Any ideas on how to reassign channel 2 (AUX) to UNTIMED and/or LATCH?

Thanks a lot!
