How to add users of a specific role to the subscriber list in RTC

Hi Team,

   We are using CLM 6.0.1. We are having one requirement like to add a list of users with a particular role  to the subscriber list.

E.g. - We are having "n" number of teams in our  project in RTC. In each  team we are having "n" number of roles .

Our requirement is  if we create a work item in a Team Area, then all the users with a specific role will be automatically added to the Subscriber list.

Thanks in Advance,
