Hello,

Group events will stay grouped until you hit ctrl-U (apple-U).

Here's how I did it this weekend. When a take was done recording and I hit stop, all the events that just recorded are automatically selected. So I hit ctrl-G there. But sometimes, I'm a bit absent minded and I forgot. In which case I usually just move the start point of take 5 over, so I can ensnare all the tracks of take 4 and then group them. Be careful there no to leave the tracks of take 5 selected, so you don't end up with all of them highlighted together.

Another quick way is my using the Move to Back command. This way I can quickly see another take and group it. I hope this helps.
