It is my understanding that once an unknown lead becomes known, their activity history is then pushed into SFDC. I want ALL their activity history from their unknown status to be pushed into SFDC. Some of these contacts had 6+ touch points before they became known. As a marketer, I can see that valuable information. If I could push that historical data to SFDC, the sale team could make an informed call relevant to their interests. Is there any way I can do this?
This is not precisely true.
You could force this through some methods.
