Setting the policy allows merging of selected policies when they come from different sources, with the same scopes and level.
If a policy is in the list and there's conflict between sources with:
* The same scopes and level: The values merge into a new policy list.
* Different scopes or level: The policy with the highest priority applies.
If a policy isn't in the list and there's conflict between sources, scopes, or level, the policy with the highest priority applies.
