Hey @Katie_Cook1 welcome to the Asana Community Forum👋
Here was a discussion about this topic as well.
I also agree that it might be best just setting up a specific project per executive and then any approvals add to this project.
In my opinion they should use Asana as then they would also receive the notifications about new approvals as well. And if they want they can even enable Asana email notifications.
Additionally you could set up various rules such as for example once they attended they are removed as follower and the task is removed from their project to avoid creating unnecessary buzz for updates they might not need.
