Automatic layer break? How?

[Granite]

I've seen references to setting layer break to automatic, but I can't find a setting to allow that. Anybody know? Thanks. I'd like to just have it choose the best one it can find and keep going.

There isn't one.

 

If you're just building ISO files that you'll never burn, you can fool it into not asking you to select a layer break position by making single layer media look bigger than it actually on the 'Media' tab.
