Edit/Associate a visitor manually

Edit/Associate a visitor manually

I am testing the SalesIQ system.  If website visitor happens to call us instead of using the web chat or web form, is there a way the person that is speaking with them can manually click the visitorID and either make them a new lead or associate them with a contact/lead in ZohoCRM manually?  It's not a perfect system, because they might link the wrong visitor, but it's one of the only ways to capture the original lead source (adwords, etc) for offline phone calls.
