There are some ways you can organize your qualifiers for easier classification. You can use masking or wildcard notation as a way of grouping work to the same service class or report class. Or, you could set up a qualifier group for any qualifier except Priority and zEnterprise service class name.
If you have more than five rules at a given level for the same classification qualifier within a subsystem type, there may be performance implications. Qualifier groups are quicker to check than a single rule, so it may make sense to use them for performance sensitive subsystems like CICS® and IMS™.
