Sorry but I still don’t get it… I don’t understand totaly groups.
Here you can add as much output as you want.
Just make sure you have the right condition to orient the data to the right output.
Condition should give values between 0 and your number of groups. You zoom on Stream gate component, hit the “plus” button until there is enough output and connect what needs to be connected
Sorry but I cannot help more than this with your description of your needs…
