Possibility to disable automatic association to deals

I’m jumping on this train as well. We are having the same situation where ONE Contact is associated with multiple internal users. When a user here emails the contact it auto-associates the email to ALL the Open-Deals associated with that contact, when in reality it only applys to one deal, or maybe not any deals. It’s an inconvenience to have to go back through the activity feed and dis-associated all of deals from the emails. And an even bigger invconvenience when my users question me 100XXX a day regarding this.
