How to assign all tasks in a task list to a user, rather than assigning each task one at a time?

How to assign all tasks in a task list to a user, rather than assigning each task one at a time?

If I have a task list that has 30 tasks, is there a faster way to make that entire list of tasks assigned to one user?

Right now I'm having to go through each task one at a time and assign each one. This is pretty slow, especially if we want to fire up multiple projects utilizing this task list template.
