This wizard will allow you to set open, due, and answer dates for problems. You will be asked to select a problem, what kind of date you want to set, and for whom the date should be effective.
After the wizard is done, you will be shown where in the advanced interface you would have gone to change the parameter you have chosen, so in the future you can do it directly.
