Using folder group edit is not the only way… you can also use use the commands in the Project>Track Versions menu to set several tracks to the same ID- then you can control which version you want to work on using the other commands in that menu- Select Tracks with Same ID will select all tracks that have a version with the same ID as the selected track.
Then, your tracks will be in sync as you switch through them using Next and Previous versions commands. (they remain selected, so you might have to change your Track Follows Event Selection pref)
I think it’s harder to explain than to actually do.
And, to pick up on what Winter Rat was saying, if you can take the time to experiment with features, there’s a lot to discover.
