This feature is a must have - it is quite limiting to only know someone is a global bounce because you have to chase down the contact uniquely then enter into their record. Major misuse of my time when there is already data on the back-end flagging these emails - we just need a filter option so we can properly manage our contacts. Keeping a globally bounce email in my contact repository is bad practice, yet I have no way to quickly identify all those that have globally bounced and clean up my database.
