Fixture Types Toolbar

Hi there so I might be going crazy, but about a year ago i was able to separate my desk channels into smaller fixture types (with a black heading above stating what they were) which then gave me them as 'fixture type' in the tool bar. I cannot remember how I did this. Can anyone give a suggestion? I know i didnt create a custom instrument because I was able to separate LED lights into these groups based on location.
