Change a few things in the Joomla Component Matukio

I am using the Joomla component Matukio but i want to change the following things: - The event must be sorted on: "current event" and "begin" - I want a checkbox with yes and no under a bookingfield (if the customer select no there must be a order bookingfield where they can fill a order option) - And I want the option to print a list from the backend with information from the bookingsfield.
