how to add large channel gap to fixture file?

[shivahoj]

hello, I have a Laser Controller, that is using the channels 1-31, and then 65 to 94, with channels 32-64 unused.
i want to control this device via midi, from an extra universe on a QLC Control PC running linux.
The laser controller does react on the faders of the "Simple desk", and so I wanted to control all its "bells and whistles"...
I started creating a fixture definition, but how do I enter this unusual fixture Channel layout?

dummy channel 32 to 64. So your fixture isn't using bits 6 and 7... odd situation
