I agree will all of the above. Our technical sales staff use tasks in HubSpot CRM but they also contribute heavily to our marketing content. I would love to be able to create marketing project tasks and have these show up on their HubSpot CRM task list. I have spoken to our sales staff about this and they agree. They want one place to see both marketing and sales related tasks.
At a minimum, maybe this functionality should be introduced at the workflow level? A new task created in Projects triggers a workflow that creates a task in HubSpot CRM. Right now, I cannot see a way to use a task as a trigger.
