I've reviewed the documentation, but the security permissions don't seem to include actual field values from the issues being reviewed.
I can see where Group-A can have permission to view/update Field-A, but I'm wondering if you can setup the following permission types:
Group-A has view/update of Field-A IF Field-B = Value-B or Field-C = Value-C
or
McDonald's Group has view/update access to Sensitive-Data-Field IF Client = McDonald's or Platform = MCD.
Is this possible? Based on the few screenshots I saw, it doesn't appear to be this robust.
