The bin/sequel -C feature is bare bones and mostly serves as a quick and dirty way to convert databases. It is not designed to handle all use cases. For anything where it doesn't do what you want, you should use the Sequel API directly. To start, you can copy the code out of the bin/sequel file to a separate file, and modify it as appropriate for your use case. I do think the documentation should probably make this clear, I'll try to update it before the next release.
