You can change an existing rule to an Expert rule if you want to add operations or actions not available in its current rule type.
When you make this change, the menu choices you began with must be converted to the correct checkboxes in Expert Mode.
Important: Avoid changing rules from expert to non-expert mode. Many of the operations and actions in Expert rules are not available to other rule types. Also, you can lose your rule definition entirely or convert the rule to something that does not match the operations or take the actions you want.
