Customizing event adding page

Hello
I have been using Event Booking extension for months now and I am very pleased.
As I have to add hundreds of event every month I would like to customize the new event adding "Basic Information" page, to simplify adding event.

Refering to the image:
1. As Marked n the green box u can set the event time. Is it possible to customize adding time to 24h timing (because I live in the 24h time zone). I mean that I don't have to use AM and PM settings, but hours 1 - 24.

2. As marked in the red box, I always use only "Only individual registration" setting. By default it is set to "Both individual and group..". I would like to change the line up of these settings. In the first place is Only indivi... and second is both individiual... . This customization I would like to use because sometimes I make mistakes and forgot to change it to "only indivi..." option. (but it always has to be only indivi...). When this option is in the first place then I wouldn't have to touch it at all.

3. Is it possible to add custom field from "extra information" tab to "basic information" page?



Thank you for your time!
Best regards,
Gert
