Aurena Configuration Context Mappings

Does anyone have an example of how they are configuring/managing contexts in IFS Aurena?

Specifically for elevated permission sets in IFS 10.

Example:

I could create a context called base sales and configure a read only sales profile to the respective usergroup mapping.

I could create a context called salesAdmin and configure a sales Admin who can change data in screens to the USERGROUP = RSM

But what about the one off scenarios of users who are in the base sales user group whom do not have admin permission set but need elevated privileges in Aurena (Edit data or see additional screens)

From my understanding, They cannot simply be added to the salesAdmin context or group of users since Aurena takes the highest level of permissions for contexts a user is apart of.

How do you go about configuring context mappings for these 3 scenarios? 

1. Base sales profile
2. Sales admin profile
3. Base sales profile with additional permission sets/privledges (but is not an admin)

Thanks,
