How to change the DMX channel numbers within the DMX Fixture Library template U5.1

When adding attributes for new fixtures, how can you change the Channel Number so its not sequential?

In the template version you can see below it’s out of sequence i.e. CH 9 and 11

In my example I would map for a BP_WashLED fixture

1 Pan
3 Tilt
6 Dimmer
8 Strobe (not available)
17 Colour
18 Zoom
