- load the first insert you want to have in a group-track like a synth to a midi-track
- route all tracks you want to group to this fx instead of to a master-out
- load all subsequent group-inserts as normal track-inserts to the midi-track
- done
it's really that simple and it works and all group-inserts are automatable... - I guess this functionality was always there - we just didn't realize it...
b.t.w.: with that technique you can even group group-tracks...
