Access to Salesforce Campaign Members in HubSpot Workflow

HubSpot Ideas
1

when a lead or Contact added to Salesforce Campaign , integration brings in the Salesforce Campaign Id into HubSpot’s Contact.

However , if we want to update the campaign member’s status back to Salesforce , workflows in HubSpot does not have access to Campaign member fileds from salesforce ?

has any one done this ?
