Including Campaign Member Fields

[Anonymous]

It's be great if Marketo could pull in the custom Campaign Member fields.  It would be even better if we could update these fields with Marketo. 
Example: tracking session preferences (attending AM or PM)  for an upcoming event using our custom campaign member fields

That's a brilliant sharing. It's definitely a pain point for using Marketo.

I am just wondering if your approach work for existing consumer that has been converted to Person Account in SFDC? If yes, should I put the custom placeholder field at the Person Account object and change the criteria accordingly?
