I suggest to make avaliable an option to filter using a 'except'/'not' clause, on Service Center logs.As today it is, we can filter most logs in Service Center by a lot of options, making it easy to track an app/espace/message while searching for something specific...On the other hand, when you are doing the oposite, like looking through all messagens in search for something amiss or out of place, having the same app/espace appearing over and over again, makes things a lot more challenging... specially when you need to pass through pages of the same content...
