Automate following with Global Follow settings?

Currently it seems that when we assign someone a task, that task automatically gets followed for that user in their inbox. Our edit is always changing, and I’d like to be able to notify our users when the cut length, etc changes, but those fields are only available on a Shot entity.

Do my users need to follow every Shot entity manually, or is there a way to automate that when we assign (or unfollow if we unassign) a Task to a user?

Or is there a way of following a Field change from a linked field? As in, I’m following the task, I would like to get updates from the Cut Length from the Shot.

Thanks
