Enable sequence assignment (Sequential) by LOCATION
Go to the fixtures tab, sort by location (by clicking the header), and select all the fixtures for a specific location, then add anything in sequential order that you want.
Hello Florian, yes, I know the possibility.
But I'll give you a practical example: I have a 25-story building and I want to locate 4 fixtures per floor on the north, west, south and east sides.
Try doing this through by the fixtures tab.
