SAP APO CIF Issues

1. We stop the CIF queue when we are running our batch planning run because we have been burned before where a user was updating a planned order and the optimizer did not save the results. It appears it can only be stopped at a global level. This will not be acceptable when we begin to roll out across multiple regions. Is there a way to shut down the CIF at a plant level ?

2. The CIF error queues are also global and users will only be interested in displaying CIF queue errors by plant. Is there a way to do this?
