[Commons-Configuration]: Nested macro property replacement

I am using the latest commons configuration with JDK1.6.

Could I do the following property replacement using the
PropertyConfigufrator?

  propA=value1
  propB=value2
  propA.value2.custom=111
  prop.custom=${propA.${propB}.custom}

Thanks!

I think, this is not possible.

Internally configuration uses the StrSubstitutor class from commons lang 
[1] for replacing variables. This class does not seem to support nested 
variables.
