Adding new features to EventOn Plugin - Wordpress

PLEASE READ THE DETAILS CAREFULLY until the bottom of project details. Hello Freelancer, I am looking for an expert coder experienced in Wordpress plugins to customise a paid Plugin called EventOn. The EventOn Plugin is capable of creating a repeating event for every day in a way that there will be only one actual event created and there will instance for every upcoming date. Everything in the front end is just fine but we are facing issues when "adding a new order" from the backend using Woocommerce. When adding a manual order from the backend using Woocommerce, we only get to add the mother event which is the original event created on the first date. We like to be able to select the future event instance date meaning it also take in records the event stock changes. So here are the tasks to complete: 1. Manual bookings from the backend (Ability to select the future repeating instance 2. Add Event Type column from EventOn Plugin, Add the order notes & Add Event Type Filter Woocomerce Order list layout 3. Update the "Reduce stock of manual orders for WooCommerce" plugin so it won't​ reduce stock when orders "On Hold" Status 4. Add Order notes block to the single orders and order list in woocommerce 5. The Customised Plugin 
Everything has to be developed in an isolated plugin without modify core files of EventOn Plugin. In the plugin settings I like to have ability to turn on/off the features.
