Hi - just wondering if it was possible to overwrite a field in SFDC with blank information from Marketo?
For example, just say, a number of incorrect Last Names have been synced to SFDC. So to correct this I want to upload a file with just the email address and new 'blank' last name so Marketo updates the SFDC or resets it.... Then the next time a customer completes a form the correct information will be synced between Marketo and Salesforce.
Hopefully do-able? (please!)
