Any way for executive user to only see tasks they created?

Presently an executive can indeed see all tasks for the project in which they have access. They do have a limited view and don't see all of the task details, but it is an "all" or "not" in regards to which tasks. Task cannot be marked as "private". An interesting idea for sure, I'm curious to see what others think.

On a tangent topic, we are contemplating allowing executives to make comments on tasks and for the other user levels to "allow executive users to view this comment". We are envisioning it working very similar to how documents currently work.
