Improve Adding Special Dates

When adding special events with multiple dates you have to click through all of the months on the pop-up calendar for both the start and end date. It would save a lot of time if selecting a start date would automatically move the ending date calendar to the same month. Also, when inputing a large list of dates it would be helpful if the pop-out calendar reverted to the last month that you entered a date for. This would eliminate a lot of extra time spent clicking through the calendar every single time for each event.
