Hey @Melissa_P,
It is not possible with Harvest as far as I know. But you can check Everhour + Asana integration instead.
When you connect Asana with Everhour, we sync all your active projects so that you don’t need to make any additional project setup. The synchronization happens automatically.
When you add a new project or change the name of the existing one, we will sync this change after some time. That means your reports will always show the freshest data.
And we also sync such meta information as tags, sections, custom fields. You can do any kind of reports in Everhour based on these details.
You can also set time estimates right inside Asana interface so at any time you can see the time you spend and what is left.
