how do you set up coverage restrictions for benefit plans?

We are on PUM 33 9.2 HCM.  I am trying to figure out the path for setting up coverage restrictions.  I can find the path for the EOI set up on the benefit plan, but there are other screens mentioned in numerous documents that I can't find.  I found a role mentioned called US Super HRMS Manager, but we don't seem to have this role available?  Any help/direction you could give would be greatly appreciated.
