Hi,
I'd like to suggest a feature to enable PMs to lock a task to prevent further time from being tracked against it.
It would be even better if this was status dependent. For example, when a task is marked as complete, there should be an option to prevent any further time being tracked against it. There could also be a related automation that would use the status change as a trigger, then apply the timelog lock.
I'm surprised this isn't already a feature to be honest! I'd love to know if anyone else has this need.
