There is a file config-paths.cfg, two directories up from the binary, which points to the config directory with file config.ini inside. In this file, there is a section "paths" and inside it variable "write-data", which you can change to point anywhere you like. This directory contains four subdirs: saves, mods, scenarios and temp, so you would probably have to share these as well (unless you want to do some symlink trickery, but then you wouldn't need moving the directory in the first place).
