Track Opportunities on Lead Object in Marketo Measure / Bizible?

Hi all, I am curious if anyone has successfully been able to track Opportunities on the Lead object within Bizible? We have a business case in which Leads have associated Opportunities in SFDC, and have been told Bizible cannot support pipeline reporting on any Opps associated to Leads. Currently exploring "workarounds" and wanted to hear if anyone else has experienced this / has ideas to solve it?
