Right now you can specify a layout for the whole book, but not individual movements' \score {} blocks. \overrides and the like can go in the time_signature.ly file, but it would be cleaner to have context-modifying overrides in the main .ly file. It would also enable the use of paper variables like system-count that can also be added to layout blocks.
