Check list assign person
Ability to assign an item on a check list to a person not just the whole task.
Matthew Bassett commented
When check list item is assigned, that person also should appear in the assigned list for the task (with a badge to show they are assigned only a check list item, unless they were already assigned for the whole task). When someone checks that assigned check list item, the person assigned is automatically removed from the list of people assigned to the task.
Makes it possible to have a process flow involving multiple people (e.g. generate, review, update, approve, etc.)
