Allow a report to pull in columns from another report, even if they are not related. It would be great to build reports that have data from multiple Smart Lists. For example, a report that shows the Leads created per week, the Leads Sent to SFDC by week (Lead may have been created anytime), Leads returned to Marketing (may have been created anytime), Leads rejected by Sales (created this month), Total Leads rejected by Sales for the Month (may have been created anytime. I know I can pull four reports and put them together in Excel. But it would be great to build these in Marketo and setup subscriptions for Sales and Marketing.
