I'm creating a FireFox addon that uses chunking to get individual file sizes down to below the limit of js files within an addon. This works great except for the 'initial' file, which I understand to be the entry point files I've specified. I understand why this is done, but want to be able to somehow define how these entry point files get split such that I can control what they're called. I can then add references to these wherever needed elsewhere in my extension.

How can I control chunking of the initial files, ideally specifying how many files to split it into and what the names are. Or at least having predictable names?
