Summary:

I have a requirement that I add a prefix IOC to roles I have customized. When I add the IOC to the role name the role does not appear on the landing page.

I have a requirement to create some custom roles in order to restrict access to some users. If take and existing role ex. Inventory Manager and add custom to the end of the role, then it replaces the existing inventory management on the console, but if I add IOC as a prefix it does not replace the inventory management icon on the console. Would anyone know how I can get the role with the IOC prefix to appear?
