Hue/Govee Group Duration

I can set a duration for individual lights but cannot set a duration for a group of lights.

I noticed when I had single lights activated, the lights would not turn on at the same time and flash in sync.

I can get them to flash in sync when selecting the group but have no option to set the duration.

I added a custom win song but my lights seem to go start flashing about 1 second before the win song, but the lights turn off relatively quickly.
