In case of IT support teams spread on multiple sites (e.g. Technician A has an admin role for Site A, technician B has an admin role for Site B) as a supervisor for all sites and resident on site C, I would like to be able to assign tickets (or change requests) to technicians without having to make them admins of site C.
In summary: the ability to assign multiple roles to the same techincian or be able to differentiate ACL for each site within a single role
