Explanation

Custom applications are created in PAN-OS for two primary purposes: (C) to correctly identify proprietary or internally developed applications that the App-ID engine does not natively recognize - once defined, these applications appear with meaningful names in traffic logs instead of 'unknown'; and (D) to reduce the volume of unidentified traffic on the network, improving visibility and enabling more precise policy enforcement. Changing the default categorization of an existing known application (A) is accomplished through Application Override policies, not custom app definitions. Visually grouping similar applications (B) is done using Application Groups or Tags, not custom application objects.
