Thanks Iñaki... this is something that's very close in functionality of 
what I'm looking for...

Indeed, if I insert this code just before the routing decision block and 
use $var(group) as desired RURI in CR/LCR call, it should work...

I still have to work around fails and re-routing issues, but let see how 
far I can go with this approach...
