Save ditamap as FM book without chapters?

Newbee here.

Is there a way to save a ditamap from Vasont to a FM book with components and have it create a book with all the topics instead of Chapters? I would like to have one large book with chapter headings but with separate files for all the topics. Is this possible? What I get now is FM book with chapters where the files are combined into chapters.

I am using FM 12. I am extracting the ditamap and topic files from Vasont, and want to edit them as FM files and then load them back to Vasont. I do not have the plugin for FM to vasont.  Anyone have an idea of the cost of those extensions?

Thanks,

Bob
