IIRC the policy is global. You'd have to make a 'meta' policy that would
defer to 'local' policies.

However, this could be considered to be a very complex setup which you
should avoid in security context. There might be more technical reasons
that would complicate this approach too.

IMHO better: write a data-driven policy that includes all rules that are
used and have that be a reasonable global policy.
