GIO: How to combine multiple fixtures to be treated as one in effects

Question

Hello, I'm new here and new to the GIO. 
 In our location we have a lot of columns, with up to three LED-PARs around them and vertically split in two parts (above and below a balcony). For effects I would like to be able to treat all LEDs on a column as one, but I can't find how to do this in the manual. If I group them, they are still treated one after another, not at the same time. 
 Do you have any ideas how to solve this problem?

Malte, 
 
You can use subgroups to treat the entire column as one unit. This is explained in the ETC training video at:

Basically you use [Shift]+[/] to make parentheses around the channels you want to be treated as one. 
 
Hope this helps, 
Todd

Thank you Cameron, 
 
I will look into offset, :-) 
but sadly the LEDs at the columns are more like 1, 1, 2, 2, 5, 2, 1, 1, 2, ...
