How to set default value and also use Environment variable in application.conf


I want to set value for one of config variable in application.conf using environment variable. But if this env variable is not present I want to default config to a certain value instead of erring out.
Is this possible? Here is setting for reference. 

test.myframework {
host = ${TEST_HOST_NAME}
}

Here if TEST_HOST_NAME if not present can I default host to localhost?

This is described in the play documentation Production Configuration:

my.key = defaultvalue
my.key = ${?MY_KEY_ENV}
