Add a core Jira field to the Jira Cloud data sync

Is it possible to add an additional Jira Cloud field for synchronization which is not part of the core or custom fields?
For example, the percentage of subtasks done in a task or epic?

This is currently not possible.

Thanks for your feedback, @Dennis_Colic! I’ve moved your post to the Product Feedback category and I will let you know if we implement this feature in the future.
