I want to cache COUNT on 12 hours and FETCH and other querysets on 1 hour for one model (catalog.item). Can this be done through the settings or another way or not? This does't work: ``` CACHEOPS = { 'catalog.*': {'ops': {'get', 'fetch', 'aggregate', 'exists'}, 'timeout': 60*60}, 'catalog.item': {'ops': {'count'}, 'timeout': 60*60*12} } ```
