I would like to capture specific information about a task, but choose who can see this information.

Use cases:

a) A team member enters in their hours of work on a particular job, and/or the final cost. User does not want others in the team/department to see this data.

b) I make comments about the progress of a task in a custom text field. This appears in the list view. I do not want others to see this.

Thanks as always
