The Lighting Controller

Hello,
here's a little problem:
I want to assign a Briteq Power Pixel 4 (PP4) to the Pixel menu.
But Power Pixel is running in 16 Channel Mode as following
1 Red
2 Green
3 Blue
4 Dimmer
5 Red
6 Green
7 Blue
8 Dimmer
9 Red
10 Green
11 Blue
12 Dimmer
13 Red
14 Green
15 Blue
16 Dimmer
It seems to be impossible to add the PP4 to Pixel Menu - First channel ?? Last channel ??
greetings

In the "Fixtures properties", You can set "Pixels > Type > RGBW or RGBA", and it will work.
(Pixels does not manage white&amber channels with RGB pixels)
