Ability to add roles to a responsibility

As mentioned by Peter on the idea to increase the number of roles allowed to be assigned to an activity …

The ability to add Roles to a Responsibility (in addition to being able to assign named persons to a responsibility) would be great and improve the communication of process changes to the right staff.

Currently we only add staff to their job role, not to a generic responsibility as it's just not practical from a maintenance point of view to do so.

If we could assign a role to a responsibility (or vice versa) that would mean staff receive notifications for not only their specific job title activities, but also their more generic or group based responsibilities (eg Senior Leadership Group, Corp Ex, Line Manager, Business Unit Manager) that are also linked to their position.
