Unfortunately, in the distribute tool that I've mentioned here in another answer, the simplicity of the essential splitting task is not matched by the complexity and bloatedness of the user interface of distribute (because it was written to combine several tasks; although performed in stages, but still combined not in the cleanest way I could think of now).

Note that the eatFiles function prepares the layouts of the future disks as tree where the leaves are symlinks to the real files. So, it is meeting your requirement that you should be able to edit the layouts before burning. The mkisofs utility has an option to follow symlinks, which is indeed employed in the code of my mkiso function.
