Hi Mike,
Sales reps can see a timeline of Program Successes and Interesting Moments in the Opportunity Influence Analyzer via Sales Insight, even if there are no opportunities created yet. More info here: https://community.marketo.com/MarketoArticle?id=kA050000000L4bzCAC.
If it's a small number of leads and accounts, you can also export the data in the Opportunity Influence Analyzer to Excel (https://community.marketo.com/MarketoArticle?id=kA050000000LBT2CAO).
