I think Salesforce has this feature.. I want to be able to filter / search for targets that I have no history with. Meaning, no campaigns, no calls, no meetings. I just want the targets in my SugarCRM that have yet to be contacted.

Is there a way to do this in Studio? Or do I need some custom PHP?

The goal is to create a target list of only those that haven't been hit by my sales team yet. I'm surprised this isn't available already!
