It cannot be emphasized enough: you can’t expect Dorico to work this way. As @FredGUnn says, it’s a powerful program.
I admit I’ve tried this in the past with programs like Photoshop, Autocad, and some other niche professional programs like speaker modeling software. I got frustrated and quit every time. That’s because it’s the wrong approach. If I would have taken time to learn how those programs work, and started at the beginning with a guided tutorial, I would have been fine.
