It's in best practice for the user to select a due date for the tasks, however, to have to click on the date and use the calendar picker to select an exact date is a cumbersome process.
The suggestion would be to have options similar to in the Preventative Activity due date, where there are quick options (See screenshot)
The suggestion for quick options would be: 1 day, 2 days, 3 days, 1 week, 2 weeks, 1 month
This has also been asked for for "Recalls" as well!
