There is no “Pro” version of my plugin. Do you mean you bought one of the many extensions for it? There is only the free version on wordpress.org, and then several paid extensions you can buy that add more functionality (calendar view, customizer, custom fields, etc.).
Again, none of that is currently possible. If you want something custom coded, we can discuss it. Otherwise, you have posted to the correct feature request forum, so this will stay here for future consideration, but I wouldn’t get my hopes up, as it seems like a very specific need.
