Not really since you are not displaying a list value from a data field. There might be a workaround, if you’re planning to assign a fixed number of tasks per user. Eg, 3 tasks maximum, etc.
However from a UI/UX point of view I would leave the tasks stacked on top of each other with that repeating group’s cell/group set to dynamic height. This way the user can easily see all tasks at a glance without having to scroll.
