Is there a way to use a field across projects? I have an “Estimated Hours” field in several projects, but when I put a task into more than one project, or I move projects, that field duplicates the same number of projects it has been in.
There are two types of custom fields: project-specific fields and organization-wide custom fields which live in your “custom fields library”.
It sounds like your custom fields are all project-specific fields. What you want to is create them in your custom fields library. Then you can easily use them in multiple projects.
