Thanks for the feedback @Cameron_Chinatti!
Interesting question - Who are the tasks assigned to (the one’s being ticked off)? If you’re assigning tasks to people and then referencing the tasks in the summary project, surely you’d want them to be ticked off when the assignee completes the work?
Have I misunderstood?
Or, is it that you’d like to “sign off” on the work before the task is marked as complete?
In terms of suggestions, you could use a tag like “Do Not Edit” to make it clear that it’s for reference only and not to be edited. Alternatively you could add “Do not edit” to the task name, like this: “[DO NOT EDIT] Write blog post”.
