We currently add leads/contacts to a SFDC campaign if they responded (converted). This response can be a form fill, click on an email link, or event attendee depending on the campaign. Is there a way to pull a report in Marketo or SFDC that allows you to see who was added to the campaign after a specific time period. In our case, we're looking to see who was added to a campaign as a response for 2014 even if the campaign was created in 2013. Therefore using the campaign report in SFDC with a created date filter will not work for us.
