Add functionality to the Joomla component "Event Booking"

The "Event Booking" component has the possibility to create one "early bird" discount which means a discount on ticket price until a set date but there is only one occurrence of this. I would like you to enable a button to dynamically duplicate this as many times as required. It consists of three form fields - amount, type (percentage or set) and cut off date I would also like the the added functionality to choose if the amount is added or deducted from the price. There is already a dynamically added group ticket price built into the component to give some guidance on the method used for the component.
