    but we need to handle this through configuration file Like in Future we add any new scenario in the config then again we need to add a new branch in the process that we are trying to avoid.

    Hi,

    could you structure it into a subprocess with one macro parameter (containing concatenated values for example) and call that subprocess recursively? It's probably not easy but it might be the generic solution you're searching for.
