Manual Mode. Basically, that’s what I’ve always done… but for different reasons… My mind still remembers when Range Copy didn’t work reliably (10 years ago) and I’ve been gun shy ever since, which is probably unfair. But mainly I’ve noticed that when I work with ‘ranges’ the controller data/keyswitches before the beginning get lopped off… and I -need- those.
However for what you’re describing I would think Range Global Copy/Paste Time would save you -ages-.
