Thanks a lot, but I was referring to specific regions, not tracks. I'm used to creating variations on an arrangement on the same timeline, one after the other. That way if I find, say, a good EQ for an instrument phrase I don't need to change it everywhere, same with sends and such. But I'd like to be able to lock down an arrangement to prevent accidental deletion (it already happened once...) while keeping the tracks editable further down the line. I'm not sure if it's clear.
I *know* I can use folders for the same purpose but from my experience they have been totally unreliable (disappearing fades when uncollapsing, other weird things) and I'm looking for another solution (short of waiting for the "multiple songs in a project" feature).
