Our Marketing group has set a threshold for scoring prospects so that when they reach a particular level, they convey to a lead in Salesforce.  There is a field in Pardot called 'Joined Date' that depicts the date that the prospect reached that score.  I do not see a corresponding field in Salesforce that allows me to align that threshold date with my reporting. Does there exists such a field and if not, how would you recommend I leverage the SFDC reporting to capture this event in the timeline of the record?  Thank you
