Multiple intensities with fixture builder

Hello,

Today I wanted to make a fixture file for a Wash that has 3 seperate intensity and colour parameters, So that you can control the wash output in 3 parts (outer ring, middle ring and center).

I am messing around with the fixture builder and I am able to set different sub intesities, that work fine. But what I really want is to have a master and a cell for this fixture file. Like some build in RGB Led bars have, A master at for example 1 and the 3 cells at 1.1, 1.2 and 1.3

Is this possible at all via the fixture builder or do I have to send in a build request and whait for the file to get build?

Thanks in advance!

Gr, Mike
