Every time I'vd added my same event. I have to createn new event again and again even they are the same event. Altgough, Copy method is viable but it's not very fast to do. So, I suggest to make repeated event function. Of cause, user must be able to select date manually. Not by dialy weekly or monthly, but I want to select day by day.
For example, An extra class as an event on 1st, 3rd, 7th, 13th, 25th on October can be add in a single time.
