   Given the example :

expr = f[a b c] + g[b c d]

   Does anyone know a function to substitute the common elements of 
Orderless functions (like Plus and Time) ? It would be something like this :

SubstituteOrdeless [expr]

   {f[a C[1]] + g[d C[1]], {C[1] -> b c}}

   I'm developing a simple one, so any suggestions are welcome.

      Thanks in advance,
