Finder CD burning is great, apart from one thing, that disks can't be incrementally added to - i.e. written in sessions, Toast-speak.

Or did I miss something?

If I didn't, is there a hack?

In Terminal.app, 'man hdiutil'.

If you'ld rather use a gui, someone's written a wrapper for it, for a price.
