Add more controls at Run Time

Question

I am developing customized schedule generator application for which I need to design User Interface. This UI will have an option to select Date, Time and number of hours. This is simply possible by adding date/time picker control and domain control. However, there can be more than one session per day and there can be multiple dates. So I want to allow user to add more input field on UI whenever required. I want a way to give best user experience than the traditional way to give Add button to add one more set of controls:

[Date] [Time] [No Of Hours] [Add more]

[Date] [Time] [No Of Hours]

[Date] [Time] [No Of Hours]

[Date] [Time] [No Of Hours]

[Date] [Time] [No Of Hours]

[Generate]

Any suggestion on improving user experience in this case?

Answer 1

Instead of adding a new set of fields on user click what if a new field appeared after filling in the date and time. Then providing users with the ability to remove a schedule on hover of that section.
