EPAC Global settings scopes/globalNotScopes & assignment scopes.

[stateofthearb]

Hi, I'm just getting into EPAC & got a question around the application of scopes.
I've defined my scopes/globalNotScopes in the global settings, to apply these to my policy assignments my understanding is that I need to specify the scope & PAC selector again in the policy assignment. Is that the only way to do it or is there a way where I can specify use this PAC selector & it would pull the scopes/globalNotScopes from global settings? It seems odd to me that I have to define my scopes in the global settings & my assignment file, it would make sense if I could just reference the scopes already set in my global settings with a ref to the PAC selector.
