Support for multiple csv files

[scott-janes]

It would be useful to be able to have a directory containing the csv files, or symlinks to multiple csv files.

The use case is if you work for multiple teams or on multiple projects you can create a csv file per team/project that can be shared with team members (maybe with git and a symlink) so updating the csv file is simpler and less hassle.

But it means you have a separation for projects/teams/environments with out having to copy someone else's csv file, and picking and choosing what you want/don't want
