Also, and sorry for all the questions, do you typically sync all of these programs to campaigns in Salesforce? Is that a best practice? Not sure what is overkill for campaign syncing and what is best just to live in Marketo.
Hey Jackie:
1) The lightbulb with the green arrow shows up when you drag the program into an engagement program.
2) I sync the individual email cast programs to SFDC campaigns for reporting goodness. (If it can influence a lead and be considered its own initiative/program/piece of content, I turn it into a program and sync with SFDC!)
