Is it possible to load more config files from an externalized config file in Grails?

Hypothetical situation:

I have downloaded a Grails application from the web as a WAR file, foo.war. In the documentation it says that I can put my own custom configuration in /foo.groovy, because this path is included in grails.config.locations in Config.groovy. I can dump all my custom config in that one file and life is good.

How, here's my problem... The configuration for FooApp is big and hairy, and I don't want it all in one file. I would like to break it up into /bar.groovy and /baz.groovy to keep things organized. Is there a way to specify something in /foo.groovy so that FooApp will also pick up /bar.groovy and /baz.groovy and process them?

I already tried appending paths to grails.config.locations in /foo.groovy, but Grails didn't like that and threw a nasty exception on startup. I'm not sure what other approach to take.

Edit for clarity:

grails-app/conf/Config.groovy looks like this:

grails.config.locations = ["file:/foo.groovy"]

Now, without modifying grails-app/conf/Config.groovy, and only by modifying /foo.groovy, is there a way to load more config files other than /foo.groovy?

You could slurp the additional config files within foo.groovy:

foo.groovy

port {
  to {
    somewhere=8080
    another {
      place=7070
    }  
  }  
}
host = new ConfigSlurper().parse(new File("bar.groovy").toURL())

bar.groovy

to {
  somewhere="http://localhost/"
  another {
    place="https://another.place.com/"
  }
}

So within your app you have:

assert grailsApplication.config.port.to.somewhere == 8080
assert grailsApplication.config.port.to.another.place == 7070
assert grailsApplication.config.host.to.somewhere == "http://localhost/"
assert grailsApplication.config.host.to.another.place == "https://another.place.com/"
