Customize webinar registration form

I have a recurring set of webinars that requires (one) registration. Is there a way to remove the 'event description' and 'event times' that seem to populate the registration form automatically? 

My description is a bit lengthy since it is for multiple webinars, which means my actual registration questions (both stock and custom) are far down the form and require scrolling to get to, which some users may not realize. I'd love to be able to put the questions FIRST and the description SECOND but I see no way to customize. Faing that,m I'd be OK to just remove the event description on the registration form as that would be better than having to scroll so far. Is it possible to customize the registration form and remove or edit the automatically entered fields?
