typesafe配置替换相对路径

Yar*_*lav 11 substitution typesafe-config

有没有办法在替代中使用相对路径而不是绝对路径?我想写这个,这不起作用:

service {
  password = "qwerty"
  url = "http://example.com?user=John&password="${password}
}

仅适用于此案例:

service {
  password = "qwerty"
  url = "http://example.com?user=John&password="${service.password}
}
